Speaker: Brian Paljug, Temple University

Abstract: Given two homotopy algebras and an infinity-morphism between them, it is natural to ask that, if we can modify the two homotopy algebras in some structured way, can we modify the infinity-morphism in some similar way, so as to preserve the new structures? In this talk we describe a situation in which the answer is yes, and indicate how it is possible. We will also give an application of these results, to show that Tamarkin´s construction of formality morphisms is equivariant with respect to the action of the Grothendieck-Teichmuller group.
