A (0,2) Mirror Map

Ilarion V. Melnikov, M. Ronen Plesser

摘要:

研究了自反平面复曲面簇中基于Calabi-Yau超曲面的(2,2)超共形世界片理论的模空间的线性西格玛模型子空间.我们描述了一组代数坐标在这个子空间上,制定了(0,2)推广的单名因子镜像映射,并表明该映射交换的奇异轨迹的镜像半扭曲理论的主成分。在非自反简单的例子中,所提出的映射在线性西格玛模型的子族之间产生镜像同构。

英文摘要:

We study the linear sigma model subspace of the moduli space of (0,2) superconformal world-sheet theories obtained by deforming (2,2) theories based on Calabi-Yau hypersurfaces in reflexively plain toric varieties. We describe a set of algebraic coordinates on this subspace, formulate a (0,2) generalization of the monomial-divisor mirror map, and show that the map exchanges principal components of singular loci of the mirror half-twisted theories. In non-reflexively plain examples the proposed map yields a mirror isomorphism between subfamilies of linear sigma models.
