Gauged Linear Sigma Model in Geometric Phases. I
Gang Tian, Guangbo Xu
We construct a cohomological field theory for a gauged linear sigma model space in geometric phase, using the method of gauge theory and differential geometry. The cohomological fi…

Gauged linear sigma model in geometric phase. II. the virtual cycle
Gang Tian, Guangbo Xu
We provide the detailed construction of the virtual cycles needed for defining the cohomological field theory associated to a gauged linear sigma model in geometric phase.
