Topological 1D gravity, KP hierarchy, and orbifold Euler characteristics of M‾g,n
In this work we study the tau-function Z1D of the KP hierarchy specified by the topological 1D gravity. As an application, we present two types of algorithms to compute the orbifold Euler characteristics of the moduli spaces M‾g,n of stable curves. The first is to use (fat or thin) topological recur...
