Relative Quasimaps and a Quantum Lefschetz Theorem
Navid Nabijou (University of Glasgow)


The theory of stable quasimaps is an important tool in enumerative geometry, providing an alternative system of curve counts to the usual Gromov-Witten invariants. In joint work with Luca Battistella, we define moduli spaces of relative stable quasimaps to a pair , where is a hyperplane section in . Intuitively, these spaces parametrise quasimaps to with specified orders of tangency to . We apply this construction to obtain a Lefschetz-type formula, expressing certain quasimap invariants of in terms of invariants of .
