摘要
Quivers with potentials are fundamental objects in geometric representation theory and also important in Donaldson-Thomas theory of Calabi-Yau 3-categories. In this talk, we will introduce quantum corrections to such objects by counting quasimaps from curves to the critical locus of the potential. Our construction is based on the theory of gauged linear sigma model (GLSM) and uses techniques developed from the recent study of DT theory of CY 4-folds. Joint work with Gufang Zhao.
