p>Talk Title: Persistent Homology

Talk Abstract:

I will give a

brief introduction to persistent homology of a continuous
function on

a topological space. Extending the original notion to include
measurem

ents of essential classes, we get a relationship to the homology of
l

evel sets and their robustness under perturbations of the function. &
