Equivariant Derived Categories Associated to a Sum of Potentials

Lim, Bronson (University of Oregon, 2017-09-06)

We construct a semi-orthogonal decomposition for the equivariant derived category of a hypersurface associated to the sum of two potentials. More specifically, if $f,g$ are two homogeneous poynomials of degree $d$ defining ...
Gluing Bridgeland's stability conditions and Z2-equivariant sheaves on curves

Collins, John, 1981- (University of Oregon, 2009-06)

We define and study a gluing procedure for Bridgeland stability conditions in the situation where a triangulated category has a semiorthogonal decomposition. As one application, we construct an open, contractible subset U ...
