Abstract:

From the seminal papers of Witten and Kontsevich we know that the intersection theory on the moduli spaces of complex curves is described by a tau-function of the KdV integrable hierarchy. Moreover, this tau-function is given by a matrix integral and satisfies the Virasoro constraints. Recently, an open version of this intersection theory was introduced. I will show that this open version can also be naturally described by a tau-function of the integrable hierarchy (MKP in this case), and the matrix integral, Virasoro and W constraints for the open case are also simple deformations of the closed ones.
