DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AGSAGS/23/">
 Characterizations of multigraded regularity on products of projective spac
 es</a>\nby Lauren Heller (UC Berkeley) as part of American Graduate Studen
 t Algebraic Geometry Seminar\n\n\nAbstract\nEisenbud and Goto described th
 e Castelnuovo-Mumford regularity of a sheaf on projective space in terms o
 f three different properties of the corresponding graded module: its betti
  numbers\, its local cohomology\, and its truncations.  For the multigrade
 d generalization of regularity defined by Maclagan and Smith\, these three
  conditions are no longer equivalent.  I will discuss some relationships b
 etween them for sheaves on products of projective spaces.\n
