Grothendieck-Teichmller Groups, Deformation and Operads

In this lecture, we will present some basic properties and constructions of topological operads and their algebras. For an operad P, the property of having a P-algebra structure is in general not invariant under homotopy: a space which is homotopy equivalent to one carrying a P-algebra structure only has a “P-algebra structure up-to-homotopy”. We will address the questions whether these P-algebra structures up-to-homotopy can be controlled by another operad, and whether they can be “strictified” to true P-algebra structures. Much of this goes back to Boardman and Vogt’s book “Homotopy Invariant Algebraic Structures”, but can efficiently be cast in the language of Quillen model categories.
