" Combinatorial
Approaches in Homotopy Theory "
By
Stockholms University
Abstract: Topological analogues of common algebraic notions,
such as the idea of being a group, are not invariant when one passes between
spaces which are homotopy equivalent. What should a
“group up to homotopy” mean? The exploration of homotopy invariant versions of categorical and algebraic
structures has been ongoing since the early days of algebraic topology. Our
focus will be on the interface between category theory and homotopy
theory. Specifically, we will discuss aspects of the homotopy
theory of operads and props.
