Wu, Ruoxu2017-06-062017-06-062017-06-05vt_gsexam:11425http://hdl.handle.net/10919/77921This thesis is devoted to a discussion of two-dimensional theories with (0,2) supersymmetry. Examples of two-dimensional (0,2) gauged linear sigma models (GLSMs) are constructed for various spaces including Grassmannians, complete intersections in Grassmannians, and non-complete intersections such as Pfaffians. Generalizations of (2,2) Toda dual theories to (0,2) Toda-like theories are also discussed and some examples are given, including products of projective spaces and del Pezzo surfaces. Correlation functions are computed to show the examples are the correct mirror models.ETDIn CopyrightSupersymmetryMirror SymmetryTopological Field TheoryString CompactificationDissertation
