Title: Operads revisited
Speaker: Ezra Getzler
Speaker Info: Northwestern University
Brief Description:
Special Note:

I will discuss my recent preprint Operads Revisited.

Operads may be represented as symmetric monoidal functors on a small symmetric monoidal category. We discuss the axioms which must be imposed on a symmetric monoidal functor in order that it give rise to a theory similar to the theory of operads: we call such functors patterns. We also develop the enriched version of the theory, and show how it may be applied to axiomatize topological field theory.

In will also explain how this formalism establishes local presentability of categories of operads.
