Title: Some results on Seshadri constants of vector bundles
Time, day and date: 4:00:00 PM, Tuesday, June 24
Venue: Ramanujan Hall
Abstract: Seshadri constants of nef line bundles on smooth complex projective varieties were introduced by J.P. Demailly to tackle Fujita conjecture. Later on, these constants were defined by C. Hacon for nef vector bundles, and subsequently studied by Fulger-Murayama for relatively nef line bundles in a relative setting. In this talk, we will survey the known results in literature about Seshadri constants for vector bundles and will discuss our recent results on Lazarsfeld-Ein type inequality satisfied by these constants. This talk is based on joint work with Indranil Biswas and Krishna Hanumanthu.
