Junior Seminar

Mercoledì 30 novembre 2022 alle ore 14:00, F.C. Simon Schirren (Università degli Studi di Roma Tre) terrà il Junior Seminar dal titolo "Virtual Cycles - An Introduction"

Abstract: We'll start with defining the normal bundle of a smooth variety (or manifold) M and motivate the Thom isomorphism from differential geometry. This will lead us to the definition of a virtual fundamental class [M] and we'll discuss its relations to the Chow ring A*(M). After a concrete computation in a specific case, we?ll get an outlook on applications to moduli problems in sheaf theory, if time permits.
