Partition Function on Not-flat Brane

نویسنده

  • Kayoko FUJIMURA
چکیده

We show that a partition function on the not-flat D1-brane can be written in the same form as that on the flat one in α-order. In this case the information of the curvature of the brane configuration is included in tachyon beta function.

Boundary CFT Construction of D - branes in Vacuum String Field

In previous papers we built (multiple) D-branes in flat space-time as classical solutions of the string field theory based on the tachyon vacuum. In this paper we construct classical solutions describing all D-branes in any fixed space-time background defined by a two dimensional CFT of central charge 26. A key role is played by the geometrical definition of the sliver state in general boundary...

An analytic torsion for graded D-branes

I consider the semiclassical approximation of the graded Chern-Simons field theories describing certain systems of topological A type branes. I show that the semiclassical partition function can be expressed in terms of a certain (differential) numerical invariant which is a version of the analytic torsion of Ray and Singer, but associated with flat graded superbundles. I also discuss a ‘twiste...

Five-brane Effective Action in M -theory

On the world-volume of an M -theory five-brane propagates a two-form with selfdual field strength. As this field is non-Lagrangian, there is no obvious framework for determining its partition function. An analogous problem exists in Type IIB superstring theory for the self-dual five-form. The resolution of these problems and definition of the partition function is explained. A more complete ana...

Mirror Symmetry for Toric Branes on Compact Hypersurfaces

We use toric geometry to study open string mirror symmetry on compact Calabi–Yau manifolds. For a mirror pair of toric branes on a mirror pair of toric hypersurfaces we derive a canonical hypergeometric system of differential equations, whose solutions determine the open/closed string mirror maps and the partition functions for spheres and discs. We define a linear sigma model for the brane geo...
