Symplectic Techniques in Topology: An Informal Introduction
Abstract:- In geometry, there are certain structures that are "rigid" (like
Riemannian manifolds) and others that are "flexible" (like topological
manifolds). Symplectic geometry lies in between these two extremes and
incorporates some attractive features of both. One consequence is that
symplectic techniques have recently been used, to great effect, to give
combinatorial approaches to questions in topology that previously
required difficult gauge-theoretic and analytic techniques. I will
introduce symplectic structures and describe some recent developments
linking them to the study of three-dimensional manifolds and knots. No
real background will be assumed. [video]
