Title: Relative BPS state counts for toric Del Pezzo surfaces and log mirror symmetry
Date: Wed, May 14, 2014, 15:30 - 17:00
Place: Seminar Room A
Abstract: Let S be a smooth Del Pezzo surface. We introduce three seemingly unrelated sets of invariants: local BPS state counts of S, relative BPS state counts of S relative to a smooth anticanonical divisor, and generalized DT invariants of the m-loop quiver. We explain how these invariants are connected and how they provide new insight into a conjecture by Takahashi on log mirror symmetry.
