" Combinatorial Approaches in Homotopy Theory "





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.
