Title    name 2017 BK21 세미나     Title Negative curves and related asymptotic quantities   Speaker Brian Harbourne   Date 2017-04-25   Host   Place KAIST   File        Abstract : Waldschmidt constants and Seshadri constants are asymptotic measure of effectivity and nefness related to plane curves. Evaluating them is related to the occurrence of curves of negative self-intersection on blow ups of the plane. I will discuss recent work on computing and bounding these quantities.
