Title:
Uniqueness problems in symplectic topology

Abstract:
A fundamental question in symplectic topology is when the space of symplectic forms in a given cohomology class is connected. Little is known about this problem in dimensions greater than two. A longstanding conjecture asserts that the answer to the question is positive for the four-torus. In this lecture I will discuss some known results related to this question and explain Donaldson`s geometric flow approach to the uniqueness problem for hyperkaehler four manifolds. The Donaldson approach is based on an infinite dimensional hyperkaehler moment map.
