D-brane masses at special fibres of hypergeometric families of Calabi-Yau threefolds, modular forms, and periods
Kilian Bönisch, Albrecht Klemm, Emanuel Scheidegger +1
We consider the fourteen families of Calabi-Yau threefolds with one complex structure parameter and Picard-Fuchs equation of hypergeometric type, like the mirror of the quintic…
On genus one fibered Calabi-Yau threefolds with 5-sections
Johanna Knapp, Emanuel Scheidegger, Thorsten Schimannek
Elliptic and genus one fibered Calabi-Yau spaces play a prominent role in string theory and mathematics. In this article we discuss a class of genus one fibered Calabi-Yau threefol…
On the Quantum K-Theory of the Quintic
Stavros Garoufalidis, Emanuel Scheidegger
Quantum K-theory of a smooth projective variety at genus zero is a collection of integers that can be assembled into a generating series that satisfies a system of linea…
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…
Analytic Continuation of Hypergeometric Functions in the Resonant Case
Emanuel Scheidegger
We perform the analytic continuation of solutions to the hypergeometric differential equation of order to the third regular singularity, usually denoted , with the help of…
Hemisphere Partition Function and Analytic Continuation to the Conifold Point
Johanna Knapp, Mauricio Romo, Emanuel Scheidegger
We show that the hemisphere partition function for certain U(1) gauged linear sigma models (GLSMs) with D-branes is related to a particular set of Mellin-Barnes integrals which can…
