A topological Chern character for matrix factorizations
Mark Shoemaker
For a quasi-projective complex variety and a regular function, we construct a Chern character from the Grothendieck group of the category of matrix f…
Quantum spectrum and Gamma structure for standard flips
Yefeng Shen, Mark Shoemaker
We investigate the quantum spectrum and Gamma structure for projective bundles, blow-ups, and standard flips. After restricting the quantum multiplication to the exceptional curve…
Wall Crossing and the Fourier-Mukai Transform for Grassmann Flops
Nathan Priddis, Mark Shoemaker, Yaoxiong Wen
We prove the crepant transformation conjecture for relative Grassmann flops over a smooth base . We show that the -functions of the respective GIT quotients are related by an…
Seiberg-like duality for resolutions of determinantal varieties
Nathan Priddis, Mark Shoemaker, Yaoxiong Wen
We study the genus-zero Gromov-Witten theory of two natural resolutions of determinantal varieties, termed the PAX and PAXY models. We realize each resolution as lying in a quiver…
A Kleiman criterion for GIT stack quotients
Mark Shoemaker
Kleiman's criterion states that, for a projective scheme, a divisor is ample if and only if it pairs positively with every non-zero element of the closure of the cone of cu…
Towards a mirror theorem for GLSMs
Mark Shoemaker
We propose a method for computing generating functions of genus-zero invariants of a gauged linear sigma model . We show that certain derivatives of -functions of…
