题 目：On configuration space integrals

摘 要：In this talk, I will first recall the configuration space integral for classical knots, a powerful invariant first proposed by Kontsevich and further studied by many people including Bott, Taubes and Thurston. Then I will talk about Watanabe's work on the 4-dimensional Smale conjecture on the diffeomorphism group of disks. In the end, I will briefly discuss a joint work with Yi Xie regarding relation between configuration space integral and formal smooth structures. This gives an evidence towards a more general conjecture about the relation between configuration space integrals, little disk operad and embedding calculus.
