Antonella Perucca (University of Regensburg), Reductions of algebraic numbers
Number theory talk, accessible to all graduate students. Join us! Abstract: We start by considering the reductions of the integers modulo the various prime numbers. More precisely, we investigate the multiplicative order of the reductions of an integer.
We then generalize this setting to number fields and illustrate some results which are joint work with Christophe Debry.
Speaker: William Stein (SageMath, Inc. & University of Washington)
Title: What is SageMath good for?
Abstract: Answer – almost everything you do. I will talk about how you can use SageMath in teaching and research. In particular, how to use Sage to support courses involving computation, to help in collaborative writing of LaTeX documents, to contribute and improve peer reviewed implementations of algorithms, and to explore new mathematics.
Title: On the Radon Transform
Abstract: In this talk we will introduce, motivate and discuss some of the elementary properties of the Radon transform operator. We will cover a little about how to invert this operator via its adjoint (i.e. back-projection operator) and approximate identities.
