DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMI/17/">Pos
 itivity of direct image sheaves</a>\nby Yajnaseni Dutta (University of Bon
 n) as part of CMI seminar series\n\n\nAbstract\nPositivity properties of d
 irect image sheaves have deep implications in\nthe geometry of families of
  varieties. For instance\, the existence of\nenough global sections of pus
 hforwards of higher tensors of the relative\ncanonical bundle of a family\
 , puts certain restrictions on the kinds of\nvarieties that can appear on 
 the fibres etc. I will discuss some these\npositivity properties\, especia
 lly the ones that come as a generalisation\nof the Fujita conjecture and i
 ts application to the Iitaka conjecture. This is\npartially a joint work w
 ith Takumi Murayama.\n
