Gauge-fixing, semiclassical approximation and potentials for graded Chern-Simons theories
C. I. Lazaroiu, R. Roiban
We perform the Batalin-Vilkovisky analysis of gauge-fixing for graded Chern-Simons theories. Upon constructing an appropriate gauge-fixing fermion, we implement a Landau-type const…
An analytic torsion for graded D-branes
C. I. Lazaroiu
I consider the semiclassical approximation of the graded Chern-Simons field theories describing certain systems of topological A type branes in the large radius limit of Calabi-Yau…
Holomorphic potentials for graded D-branes
C. I. Lazaroiu, R. Roiban
We discuss gauge-fixing, propagators and effective potentials for topological A-brane composites in Calabi-Yau compactifications. This allows for the construction of a holomorphic…
String field theory and brane superpotentials
C. I. Lazaroiu
I discuss tree-level amplitudes in cubic topological string field theory, showing that a certain family of gauge conditions leads to an A-infty algebra of tree-level string product…
Graded Chern-Simons field theory and graded topological D-branes
C. I. Lazaroiu, R. Roiban, D. Vaman
We discuss graded D-brane systems of the topological A model on a Calabi-Yau threefold, by means of their string field theory. We give a detailed analysis of the extended string fi…
Graded Lagrangians, exotic topological D-branes and enhanced triangulated categories
C. I. Lazaroiu
I point out that (BPS saturated) A-type D-branes in superstring compactifications on Calabi-Yau threefolds correspond to {\em graded} special Lagrangian submanifolds, a particular…
