Torus Knots and the Topological Vertex
Hans Jockers, Albrecht Klemm, Masoud Soroush
We propose a class of toric Lagrangian A-branes on the resolved conifold that is suitable to describe torus knots on S^3. The key role is played by the SL(2,Z) transformation, whic…
The refined BPS index from stable pair invariants
Jinwon Choi, Sheldon Katz, Albrecht Klemm
A refinement of the stable pair invariants of Pandharipande and Thomas for non-compact Calabi-Yau spaces is introduced based on a virtual Bialynicki-Birula decomposition with respe…
ABJM Wilson loops in the Fermi gas approach
Albrecht Klemm, Marcos Marino, Marc Schiereck +1
The matrix model of ABJM theory can be formulated in terms of a Fermi gas in an external potential. We show that, in this formalism, vevs of Wilson loops correspond to averages of…
Quantum geometry of elliptic Calabi-Yau manifolds
Albrecht Klemm, Jan Manschot, Thomas Wotschke
We study the quantum geometry of the class of Calabi-Yau threefolds, which are elliptic fibrations over a two-dimensional toric base. A holomorphic anomaly equation for the topolog…
