DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VCAS/103/">S
 eshadri constants</a>\nby Krishna Hanumanthu (Chennai Mathematical Institu
 te\, Chennai) as part of IIT Bombay Virtual Commutative Algebra Seminar\n\
 n\nAbstract\nSeshadri constants of line bundles on projective varieties we
 re defined by J-P. Demailly in 1990\, motivated by an ampleness criterion 
 of C. S. Seshadri.  They are a measure of local positivity of line bundles
  and have interesting connections to different areas in mathematics. We wi
 ll discuss some important questions that drive research on Seshadri consta
 nts. We will also discuss their relationship with Waldschmidt constants wh
 ich are invariants attached to homogeneous ideals in polynomial rings.\n
