Defects as functors between phases of Abelian gauged linear sigma models

Ilka Brunner

Defects act naturally on boundary conditions, providing functors between D-brane categories. In the context of gauged linear sigma models, one can use defects to transport branes from one phase to another. In this talk, I will show how to construct such defects explicitly.
