Topological strings live on attractive manifolds
Jarah Evslin, Ruben Minasian
We add to the mounting evidence that the topological B model's normalized holomorphic three-form has integral periods by demonstrating that otherwise the B2-brane partition functio…
T-duality, Gerbes and Loop Spaces
Dmitriy M. Belov, Chris M. Hull, Ruben Minasian
We revisit sigma models on target spaces given by a principal torus fibration , and show how treating the 2-form B as a gerbe connection captures the gauging obstructions a…
D-brane Couplings, RR Fields and Clifford Multiplication
S. F. Hassan, R. Minasian
Non-trivial configurations of Yang-Mills fields and gravitational backgrounds induce charges on Dp-branes that couple them to lower and higher RR potentials. We show that these cou…
M5-branes, Special Lagrangian Submanifolds and sigma-models
Ruben Minasian, Dimitrios Tsimpis
We study M-theory fivebranes wrapped on Special Lagrangian submanifolds () in Calabi-Yau three- and fourfolds. When the M5 wraps a four-cycle, the resulting theory is a two-di…
