Recursion relations in intersection theory on the moduli spaces of Riemann surfaces
Motohico Mulase 氏 (University of California, Davis)
Recursion relations in intersection theory on the moduli spaces of Riemann surfaces
[ 講演概要 ]
In this talk I will give a survey of recent developments in the intersection theory of tautological classes on the moduli spaces of stable algebraic curves. The emphasis is placed on explaining where the Virasoro constraint conditions are originated. Recently several authors have encountered the same combinatorial recursion relation from completely different contexts, that eventually leads to the Virasoro constraint. This mysterious structure of the theory will be surveyed.
