Research Abstract

We found new recursive formulas of intersections between lambda and psi classes, which generalized formulas in a paper "Towards an enumerative geometry of the moduli space of curves" by David Munford via applying the localization theorem to the graph space of a moduli of point stable curves. We also generalized Fulton-MacPherson configuration space to relative one and compute its Chow motive.
