| Gauged Linear Sigma Models, disk partition function and nonabelian matrix factorizations |
| Speaker: | Mauricio Romo (Kavli IPMU) |
| Abstract: | I will explain how the supersymmetric disk partition function Z_{D^2}
of gauged linear sigma models relate to the central charge of objects
in the category of B-branes of a Calabi-Yau (CY). The advantage of
this approach is that Z_{D^2} provides an expression at every point
in the quantum corrected moduli space of the CY. The B-branes in
these models are realized naturally as matrix factorizations,
equivariant under the gauge group. I will explain how to relate them
to more familiar objects such as coherent sheaves on the CY and show
applications of this result to different type of CYs, including more
exotic non-complete intersections.
