Sphere partition function of Calabi-Yau GLSMs
David Erkinger, Johanna Knapp
The sphere partition function of Calabi-Yau gauged linear sigma models (GLSMs) has been shown to compute the exact Kaehler potential of the Kaehler moduli space of a Calabi-Yau. We…

D-brane central charge and Landau-Ginzburg orbifolds
Johanna Knapp, Mauricio Romo, Emanuel Scheidegger
We propose a formula for the exact central charge of a B-type D-brane that is expected to hold in all regions of the Kahler moduli space of a Calabi-Yau. For Landau-Ginzburg orbifo…
