Kurzfassung englisch:
The gauged linear sigma model (GLSM) is a supersymmetric gauge theory in two dimensions whose low energy field configurations are Calabi-Yau (CY) spaces. Non-abelian GLSMs lead to CYs which are not complete intersections in toric ambient spaces. By tuning parameters of the gauge theory one can probe the Kahler moduli space of the CY. Different parameter regions ("phases") correspond to topologically distinct CYs. D-branes in GLSMs are matrix factorizations of the GLSM superpotential. Using the hemisphere partition function one can compute the D-brane charges in the phases of the GLSM. In this talk I will explain these conception and report on work in progress with R. Eager, K. Hori and M. Romo on D-brane transport in non-abelian GLSMs.
