Query: Mirzakharni's recursion formula is equivalent to the Witten-Kontsevich
  theorem   In this paper, we give a proof of Mirzakhani's recursion formula of
Weil-Petersson volumes of moduli spaces of curves using the Witten-Kontsevich
theorem. We also describe properties of intersections numbers involving higher
degree $\kappa$ classes.
