'Around quantum j-mappings (model theory and sheaves)'.

Andres Villaveces
(Bogota)
Abstract
Abstract: finding a "non-commutative limit" of the j-invariant (to real numbers, in a way that captures reasonably well the connection with extensions of number fields) has prompted several approaches (Manin-Marcolli, Castaño-Gendron). I will describe one of these approaches in a brief way, and I will make some connections to the model theory of sheaves.

The Prime Number Theorem - Our latest Secrets of Mathematics Podcast

Prime numbers have fascinated mathematicians since there were mathematicians to be fascinated, and the Prime Number Theorem is one of the crowning achievements of the nineteenth century. The theorem answers, in a precise form, a seemingly basic question: how many prime numbers are there?

2x2 Matrices

Giles Gardam
(Oxford)
Abstract

We will explore the many guises under which groups of 2x2 matrices appear, such as isometries of the hyperbolic plane, mapping class groups and the modular group. Along the way we will learn some interesting and perhaps surprising facts.

SoapboxScience in Oxford - Data Science Demystified

Modern software allows us to draw symbols (such as Chinese characters, or mathematical symbols) that the computer will then recognise and turn into type. How can these systems be improved, so that they run faster and more accurately?
