Parking at UH

On Saturday people can park anywhere on campus for a flat fee of 5 dollars. On Sunday parking is free. However, renting a car for driving to the UH is not worth it. Parking in Waikiki is expensive and it is easy to get from Waikiki to the UH campus by bus or cab.

TheBus (

The bus fare for a single trip (any distance) plus one transfer is 2.50 dollars exact change. For seniors over 65 with a Medicare card the rate is 1 dollar.

The #4 bus runs from Kuhio Avenue to the University. Persons staying at Hokele Suites get to Kuhio Avenue in a few steps heading toward the sea (makai). People staying in the Maile Sky Court only need to look for the nearest bus stop. To get to the UH take the bus on the mountain (mauka) side of Kuhio Avenue.

People staying at the Hawaii Prince Hotel or the Hilton Hawaiian Village will have to walk 5 to 10 minutes to the #4 bus stop on the McCully Bridge over the Ala Wai Canal or take the very frequent #8 bus to the Ala Moana Shopping Center and there catch the #6 bus.

The #4 bus runs along Kuhio Ave and departs at Monsarrat/Kalakaua on Saturday at 6:00a, 6:30a, 6:58a, 7:25a, 8:15a. On Sunday departure times are 6:15a, 6:55a, 7:30a, 8:00a, 8:30a. It takes about 25 minutes to reach the UH. Monsarrat/Kalakaua is located at the Diamond Head end of Waikiki so it will take some 5 to 10 minutes for the bus to reach the other end of Kuhio Ave.

On Saturday the A City Express Bus leaves from the Ala Wai Community Park at 5:55a, 6:25a, 6:35a, 6:55a, 7:05a, 7:25a and on Sunday at 6:20a, 6:50a, 7:20a and 7:50a. The bus stop is on Kapiolani Boulevard Diamond Head of McCully Street (turn right after crossing McCully bridge coming from Waikiki). This bus takes 9 minutes to get to the UH.

The #6 bus leaves the Ala Moana Shopping Center, Kona Street (direction Woodlawn) on Saturday at 5:42a, 6:07a, 6:37a, 7:04a, 7:34a, 8:04a, 8:35a and on Sunday at 6:21a, 7:06a, 7:54a, 8:24a reaching the UH in about 10 minutes.


Cabs in Hawaii have to be pre-ordered by phone. The fare from Waikiki to the UH is 11 to 16 dollars depending on location in Waikiki. Thus sharing a cab between three or four people would be a reasonable option.


The Hilton Hawaiian Village is fronting a swimming beach. The Hawaiian Prince Hotel overlooks the yacht harbor but a short walk is required to get to a swimming beach. From the Hokele Suites and the Maile Sky Court one can reach the busy Waikiki Beach in a few minutes.

GENERAL AUDIENCE LECTURE The Right Answers to The Wrong Questions. A Brief History of Mathematics in Finance
February 2010 is the 50th anniversary of Eugene Wigner's On the Unreasonable Effectiveness of Mathematics in the Natural Sciences. In that paper, Wigner speculated that the benefits that mathematics had provided to physics might in future spread to 'wide branches of learning'. In this talk I will survey the history of attempts to apply mathematics in economics and finance. This is a story of missed opportunities in which the right answers to the wrong questions have had a large impact. While this lecture is about mathematics, it is for a general audience and assumes no specialist knowledge of mathematics or finance.
Risk (Mis)management and the Financial Crisis. The Impact of the All Too Probable
Extreme Value Theory is a branch of statistics which is over 80 years old. Expected Shortfall is the statistical term for the average loss beyond a given threshold. Using Extreme Value Theory to estimate Expected Shortfall is a common risk management practice in the insurance industry. In the Finance Industry risk 'management' has relied instead on normal distributions and Value at Risk. The failure to predict the losses that rocked markets in 2007, 2008 and 2009 was not a failure of markets or an example of the futility of attempting to predict market behavior with statistics. In this talk, I'll provide a brief introduction to the statistics of extremes and show that, if the correct tools had been used, the recent financial crisis (in common with earlier crashes) would have been seen to be all too probable. A cursory knowledge of probability and statistics is the only prerequisite for this material.
The Geometry of Probability Distributions. A New Source of Statistics
In studying probability distributions, a natural specialization is to consider distributions which have a finite mean. A recently discovered method of describing the probability distributions with this property leads naturally to an affine equivalence problem. The affine geometry of probability distributions reveals remarkable structure including a natural measure of dispersion about the mean, improvements on the Markov and Chebychev inequalities, a new affine invariant and a new central limit theorem. The talk is intended to be accessible to graduate students in Mathematics.

Invariant measures on countable models
The Erdos-RÉnyi random graph construction can be seen as inducing a probability measure concentrated on the Rado graph (sometimes known as the countable "random graph") that is invariant under arbitrary permutations of the underlying set of vertices. The following question arises naturally: On which countable combinatorial structures is there such an invariant measure? Up until recent work of Petrov and Vershik (2010), it was not even known if Henson's universal countable triangle-free graph admitted an invariant measure.
We provide a complete characterization of countable structures admitting invariant measures, in terms of the model-theoretic notion of definable closure. This leads to a characterization for ultrahomogeneous structures, as well as new examples of invariant measures on graphs, trees, and other combinatorial structures.

On some conjectures of Ron Brown and Alexander Grothendieck
Associated to a field $k$ is a lattice tower of finite Galois extension fields of $k$ and the inclusions between them, inside an algebraic closure. Associated to this tower of field extensions is the lattice tower of the finite Galois groups of the extensions and the surjections between these groups. In the late 60's and 70's, work of Neukirch, Uchida, and others led to the remarkable result that if two number fields (finite algebraic extensions of $\mathbb{Q}$ have isomorphic Galois towers (in the obvious sense of matching up the groups and surjections in the two towers) then the two number fields are actually isomorphic. In the 90's, motivated by conjectures of Grothendieck dating from the early 80's, this result was extended by Pop, Mochizuki, and others to arbitrary finitely generated fields over $\mathbb{Q}$, that is, finite algebraic extensions of the field of rational functions in $d$ variables. More precisely, Grothendieck conjectured that a certain type of comparison of the Galois towers of two such fields $K$, $L$ should correspond to inclusions $K \to L$, and this also was proved.
As an illustration of the nature of the result, if $X$ is a compact Riemann surface then its field of meromorphic functions can be expressed $E(X) = \mathbb{C}(z)[w] / (f(z, w) = 0)$, where $f(z, w)$ is a polynomial in two variables. The Galois tower of $E(X)$ depends only on the topological type of $X$, that is, its genus. But polynomial $f(z, w)$ sees only finitely many complex numbers as coefficients. We then have small subfields of the meromorphic functions, $E_K(X) = K(z)[w] / (f(z,w) = 0)$, that are finitely generated over $\mathbb{Q}$. The Galois tower of $E_K(X)$, which retains arithmetic properties of $X$, essentially determines the Riemann surface $X$ itself, inside a $6g - 6$ dimensional moduli space of Riemann surfaces of genus $g \geq 2$.
But Grothendieck conjectured more. Given a Riemann surface $X$ defined, say, by a polynomial $f(z, w)$ with $\mathbb{Q}$ coefficients, Grothendieck believed all rational solutions of the equation $f(r, s) = 0$ should be explained in terms of another type of comparison of the Galois tower of the field $\mathbb{Q}$ and the tower of the arithmetic meromorphic function field $E_{\mathbb{Q}}(X)$. [For example, a problem of some interest has been to understand rational solutions of $r^n + s^n = 1, n \geq 3$. The polynomial $z^n + w^n -1$ defines a Riemann surface of genus $g = (n-1)(n-2)/2$. The story goes that in the 80's Grothendieck thought he might be able to settle such arithmetic questions by his Galois tower considerations, or at least recover Falting's results on the finiteness of the number of rational solutions when $g \geq 2$.]
These `section conjectures' of Grothendieck remain unproved. I want to discuss some related conjectures about ordered fields that Ron Brown and I have been discussing since 2007. For example, is it possible to express the real numbers as a composite field $\mathbb{R} = \mathbb{Q}^r F$, where $\mathbb{Q}^r$ is the field of real algebraic numbers and $\mathbb{Q}^r \cap F = \mathbb{Q}$? Presumably the answer is `no', even though there are examples of such decompositions $ \mathbb{C} \simeq \mathbb{Q}^rF[i]$. (The usual conjugation in $\mathbb{C}$ badly scrambles $F$. Put another way, the field $\mathbb{Q}^r F$ here is a big ordered field, but quite different from $\mathbb{R}$. All the Dedekind cuts of $\mathbb{Q}$ determined by elements of the ordered field $F$ in known examples of such decompositions of $\mathbb{C}$ are rational cuts, or $\pm\infty$).
More generally, if $R$ is any ordered field with $R = \mathbb{Q}^r F$ as above, and such that $R[i]$ is algebraically closed, Ron has suggested exactly what the nature of the field $F$ should be. In particular, elements of $F$ should always produce rational Dedekind cuts of $\mathbb{Q}$, or $\pm\infty$. These suggestions, if true, imply some of the Grothendieck section conjectures about rational points, and seem to provide a new way of looking at the Grothendieck conjectures.

Week of Mathematics Hawai'i-Geneva 2010
UHM News Release

Abstract: An event co-organized by la Commission genevoise de l'enseignement des mathématiques (comprised of the mathematics department at the University of Geneva, Switzerland and the primary and secondary school system) and the SUPER-M project of the mathematics department at the University of Hawai‘i, USA.

For one week this initiative will bring together the primary/secondary educational systems and university faculty and students. All volunteer classrooms work around a common theme. This year's theme is folding. Folding usually suggests origami or other traditional folding but it is not on this aspect that these lessons are primarily developed: there is often little mathematics in origami, especially when the purpose is to follow a pre-designed model, or the mathematics are so complex that they are accessible only to the higher grade levels. The emphasis here is to use folding activities to generate mathematical questions in relation to different levels of mathematics.

Department of Mathematics, University of Wisconsin at Madison
Over the last 23 years, the Annual Automorphic Forms Workshop has remained a small and friendly conference. Those attending range from students, new PhD’s, and established researchers. For young researchers, the conference has provided support and encouragement. For accomplished researchers, it offers the opportunity to mentor, and it provides a forum for exchanging ideas.
The workshop has become internationally recognized for both its high-quality research talks and its supportive atmosphere for junior researchers. Participants present cutting-edge research in all areas related to automorphic forms. These include Maass wave forms, elliptic curves, Siegel and Jacobi modular forms, special values of L-functions, random matrices, quadratic forms, applications of modular forms, and many other topics.
In addition to research talks, the workshop has, in the past years, featured panel discussion sessions on the topics of grant writing, mentoring and research partnerships, REUs and outreach, and opportunities for international collaborations. Based on the success of these sessions, we plan to have similar panel sessions this year as well.

Galois Representations
Abstract: Many advances on the algebraic side of number theory in the last 15 years (such as the solutions of the Shimura-Taniyama conjecture, Sato-Tate conjecture and Serre’s conjecture, as well as decisive progress on the Fontaine-Mazur conjecture and Main Conjectures for modular forms) have relied in an essential way on improvements in the theory of Galois representations.
The aim of the three main courses is to present an overview of many of these ideas and applications, aimed at advanced graduate students and postdocs with a strong background in number theory, Galois cohomology, and basic algebraic geometry.
