Poisson流形上的D-膜与广义几何

D-brane on Poisson manifold and Generalized Geometry

T. Asakawa, H. Muraki, S. Watamura

摘要:

利用Dirac结构的两种变形,分别基于B变换和β变换,研究了D膜涨落的性质.前者给出了具有2形式场强的标准规范理论。后者给出了Poisson流形上的一个非标准规范理论,该规范理论具有双矢量场强度和作为规范势的矢量场,其中的规范对称性是由Hamilton矢量场生成的一个非标准规范.利用Moser引理和Magnus展开,构造了两个规范理论之间的映射.我们还研究了非对易D-膜与规范理论的关系。

英文摘要:

The properties of the D-brane fluctuations are investigated using the two types of deformation of the Dirac structure, based on the B-transformation and the beta-transformation, respectively. The former gives the standard gauge theory with 2-form field strength. The latter gives a non-standard gauge theory on the Poisson manifold with bivector field strength and the vector field as a gauge potential, where the gauge symmetry is a diffeomorphism generated by the Hamiltonian vector field. The map between the two gauge theories is also constructed with the help of Moser's Lemma and the Magnus expansion. We also investigate the relation to the gauge theory on the noncommutative D-branes.
