Abstract

We demonstrate the equivalence of Virasoro constraints imposed on the continuum limit of the partition function of the hermitean one-matrix model and the Ward indentities of Kontsevich's model. Since the first model describes ordinary d = 2 quantum gravity, while the second one is supposed to coincide with Witten's topological gravity, the result provides a strong implication that the two models are indeed the same.
