Abstract:
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.
