Asymmetry and Duality in Topology

The talk will be suitable for a general audience.

Students are strongly encouraged to participate.

Abstract


It turns out that the traditional separation axioms (eg., Hausdorff, completely regular) can be viewed as a relationship that may hold between two topologies on a set. This view leads to dualities among topologies, which behave in many ways like the traditional "opposite ring" or "dual category" dualities. We discuss this framework and some applications.
