Seminar

Postdoc day, Seminar 4: Formality and non-zero degree maps

Higher algebraic structures in algebra, topology and geometry

11 February 15:50 - 16:20

Aleksandar Milivojevic - Stony Brook University

Given the existence of a non-zero degree map between spaces satisfying rational Poincaré duality, does it follow that the target is formal if the domain is formal (in the rational homotopy theoretic sense)? I will discuss some results pointing towards a potential positive answer, both in the topological and holomorphic settings, where in the latter Serre duality plays the role of Poincaré duality and there are several contenders for a correct notion of formality.
