SUMMARY:Hodge structures through Topological Quantum Field Theory - Angel 
 Gonzalez Prieto (UCM Madrid)
DTSTART:20180223T150000Z

CONTACT:Nils Prigge
DESCRIPTION:Topological Quantum Field Theories are powerful categorical to
 ols that provide deep insight into the behaviour of topological invariants
  under gluing. In this talk\, we will review some properties of TQFT\, inc
 luding duality and classification problems\, as well as their lax counterp
 arts and how to construct them.\n\nUsing this procedure\, we will construc
 t a lax monoidal TQFT that computes the mixed Hodge structure on the cohom
 ology of representation varieties. For that\, Saito's mixed Hodge modules 
 will play an important role as quantizations of Hodge structures.\n\nJoint
  work with M. Logares and V. Muñoz.
