SpeakerDu Pei is currently an associate professor of quantum mathematics at the University of Southern Denmark. He obtained his Ph.D. in theoretical physics in 2016 from Caltech. His main research interests concern the geometric, algebraic and categorical properties of quantum field theory.AbstractThe existence of quantum field theories in higher dimensions predicts many hidden algebraic struct...
Abstract A representation of a group G is said to be rigid, if it cannot be continuously deformed to a non-isomorphic representation. If G happens to be the fundamental group of a complex projective manifold, rigid representations are conjectured (by Simpson) to be of geometric origin. In this talk I will outline the basic properties of rigid local systems and discuss several consequences of Si...
