A reconstruction theorem for genus zero Gromov-Witten invariants of stacks
Rose, Michael A.
Original · EN
We generalize the First Reconstruction Theorem of Kontsevich and Manin in two respects. First, we allow the target space to be a Deligne-Mumford stack. Second, under some convergence assumptions, we show it suffices to check the hypothesis of H²-generation not on the cohomology ring, but on an any quantum ring in the family given by small quantum cohomology.
