Changho Han, Trigonal Curves and Associated K3 Surfaces
B236-1 IBS, Korea, Republic ofSpeaker Changho Han Korea university K3 surfaces, as a generalization of elliptic curves, have a rich amount of geometric properties. Recalling that elliptic curves are double covers of …
Justin Lacini, On Log del Pezzo Surfaces in Positive Characteristic
B236-1 IBS, Korea, Republic ofSpeaker Justin Lacini Princeton university A log del Pezzo surface is a normal surface with only Kawamata log terminal singularities and anti-ample canonical class. Over the complex numbers, …
David Sykes, CR Hypersurfaces, Studying 2-nondegenerate Structures via Absolute Parallelisms
B236-1 IBS, Korea, Republic ofSpeaker David Sykes IBS CCG The basic problem of finding (local) biholomorphisms mapping one real hypersurface in a complex space onto another is only well understood for a …
