Title: Commutators and BMO

Abstract: In this talk we will discuss the connection between functions with bounded mean oscillation (BMO) and commutators of Calderon-Zygmund operators. In particular, we will discuss how to characterize certain BMO spaces related to second order differential operators in terms of Riesz transforms adapted to the operator and how to characterize commutators when acting on weighted Lebesgue spaces.

Title: Two Weight Estimates for Commutators

Abstract: In this talk we discuss a modern proof of a result by Bloom
which characterizes when the commutator of a function and the Hilbert
transform is bounded on weighted L^p spaces. Our method of proof
extends Bloom’s result to all dimensions and Calderon-Zygmund
operators. This talk is based on joint work with Irina Holmes and
Michael Lacey.

Title: WEAK AMENABILITY IS STABLE UNDER GRAPH PRODUCTS

Dissertation Draft

Abstract: Weak amenability of discrete groups was introduced by Haagerup and co-authors in the 1980’s. It is an approximation property known to be stable under direct products and free products. In this thesis we show that graph products of weakly amenable discrete groups are weakly amenable (with Cowling-Haagerup constant 1). Along the way we construct a wall space associated to the word length structure of a graph product and also give a method for extending completely bounded functions on discrete groups to a completely bounded function on their graph product.
