Quantum cohomology of blowups
Published 25 Jul 2023 in math.AG and math.SG | (2307.13555v3)
Abstract: We prove a decomposition theorem of the quantum cohomology D-module of the blowup of a smooth projective variety X along a smooth subvariety Z. The main tools we use are shift operators and Fourier analysis for equivariant quantum cohomology.
