I will give an introduction to the topic of this semester’s seminar: the automorphisms of E_n-operads. Our main goal is to understand the computation of Fresse, Turchin and Willwacher of the rational homotopy of Map^h(E_m,E_n^Q) in terms of graph homology. We then discuss some potential applications, and lines of inquiry opened up by this result. This connects the topic to differential topology and number theory.
