Higher dimensional cobordism categories and their topology

Tillmann, U (Oxford)

We will discuss how to define a strict higher dimensional version of the cobordism category, associate a topological space to them, and explain how these spaces relate to classical spaces in cobordism theory as studied by Thom and others in the middle of the last century.
