Houston Kirk Colloquium: "Special Divisors of Del Pezzo Surfaces Along the Gosset Polytopes"

Professor Jaehyouk Lee, Ewha Womans University, Seoul

Abstract: In this talk, we consider special divisors (root, line, ruling, exceptional system ) classes of del Pezzo surfaces and their correspondences to subpolytopes in Gosset polytopes k21.  And we introduce configuration of lines along the correspondences. We also discuss an application of rational quartic divisors and the related contraction of del Pezzo surface.
