Title: Absolute and relative quantum cohomology

Abstract: In a joint work with Longting Wu and Fenglong You, we defined relative quantum cohomology rings by introducing relative Gromov-Witten invariants with negative contact orders. I will compare the definitions of absolute and relative quantum rings, try to explain how the WDVV equation (associativity) motivates our definition of negative contacts, and perhaps show some examples if time permits.
