DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/114/">Ho
 dge sheaves for singular families</a>\nby Sandor Kovacs (University of Was
 hington) as part of ZAG (Zoom Algebraic Geometry) seminar\n\n\nAbstract\nT
 his is a report on joint work with Behrouz Taji. Given a flat projective m
 orphism [f:X\\to B]  of complex varieties\, assuming that [B]  is smooth\,
  we construct a system of reflexive Hodge sheaves on [B] . If in addition 
 [X]  is also smooth then this system gives an extension of the Hodge bundl
 e underlying the VHS of the smooth locus of [f] . This in turn provides a 
 criterion that all VHSs of geometric origin must satisfy. As an independen
 t application we prove a singular version of Viehweg's conjecture about ba
 se spaces of families of maximal variation.\n
