Quantum Cohomology and Crepant Resolutions: A Conjecture
Tom Coates, Yongbin Ruan
We give an expository account of a conjecture, developed by Coates--Corti--Iritani--Tseng and Ruan, which relates the quantum cohomology of a Gorenstein orbifold X to the quantum c…

The Crepant Resolution Conjecture for Type A Surface Singularities
Tom Coates, Alessio Corti, Hiroshi Iritani +1
Let X be an orbifold with crepant resolution Y. The Crepant Resolution Conjectures of Ruan and Bryan-Graber assert, roughly speaking, that the quantum cohomology of X becomes isomo…
