Lecturers & Examiners: Prof. Dr. Paul Biran
Number of participants limited to 12.

Abstract

In this seminar, we will define quasimorphisms and use them as an algebraic tool to study various automorphism groups of manifolds. After a short introduction to symplectic geometry, we will mainly focus on the group of Hamiltonian diffeomorphisms and Calabi quasimorphisms.

Objective

By giving two half-hour talks, typing short summaries for those talks and participating in talks by others, each participant will get familiar with the concept of quasimorphisms, learn about some concrete examples in and outside the world of symplectic geometry, as well as develop presentation and collaboration skills.
