Algebraic Geometry Seminar: The zero locus of an admissible normal function
- Date: 10/19/2009
Lecturer(s):
Patrick Brosnan (UBC)
Location:
University of British Columbia
Description:
If H is a variation of Hodge structure over a variety S, then there is a family of complex tori J(H) over S associated to H. Admissible normal functions are certain sections of J(H) over S. Roughly speaking, they are the ones that have the possibility of coming from algebraic geometry.
I will explain recent work with Gregory Pearlstein proving that the locus where a section of J(H) vanishes is an algebraic subvariety of S. This answers a conjecture of Griffiths and Green.
