西格玛模型中的伪对偶和复几何

Pseudoduality and Complex Geometry in Sigma Models

Mustafa Sarisaman

摘要:

研究了Kähler流形上二维N =(2,2)西格玛模型的伪对偶变换.证明了目标空间上的结构可以通过保(反)全纯映射变换到伪对偶流形上。这个映射要求伪对偶流形上与各个空间和黎曼联络有关的挠率为零。我们还考虑了全纯同构,这使得额外的限制的伪对偶。

英文摘要:

We study the pseudoduality transformations in two dimensional N = (2, 2) sigma models on Kähler manifolds. We show that structures on the target space can be transformed into the pseudodual manifolds by means of (anti)holomorphic preserving mapping. This map requires that torsions related to individual spaces and riemann connection on pseudodual manifold must vanish. We also consider holomorphic isometries which puts additional constraints on the pseudoduality.
