Gravitational Dressing of Renormalization Group
I. R. Klebanov, I. I. Kogan, A. M. Polyakov
Abstract
We study the gravitational dressing of renormalizable two-dimensional field theories. Our main result is that the one-loop β-function is finitely renormalized by the factor k+2 k+1, where k is the central charge of the gravitational SL(2, R) current algebra.
