The main aim of Mic Seminars is to bring together young mathematicians from different universities. It provides an informal context to share knowledge and ideas, and to build social networks within the different mathematical communities.
The next talk is on the 10th of February at 17:00, in room 2AB45.

Title: On the class group of cyclotomic fields
Abstract: Class groups of fields give important information about unique factorisation in their ring of integers, in particular they played a major role in the study of Fermat's Last Theorem. In this talk we will first introduce what class groups are and then, following the last 200 years of mathematical progress in the topic, introduce Ribet's Method, a powerful technique combining modular forms and Galois representations, used to study class groups. We will end with a new cohomological approach to this method.
