$W_{\infty} Algebra in Two-Dimensional Black Hole

High Energy Physics - Theory 2011-04-20 v1

Abstract

We study the SL(2;R)/U(1)SL(2;R)/U(1) coset model of two-dimensional black hole and its relation to the Liouville theory coupled to c=1 matter. We uncover a basic isomorphism in the algebraic structures of these theories and show that the black hole model has the same physical spectrum as the c=1 model, i.e. tachyons, WW_\infty currents and the ground ring elements. we also identify the operator responsible for the creation of the mass of the black hole.
