Abstract
We compute the one-loop beta functions of the cosmological constant, Newton's constant and the topological mass in topologically massive supergravity in three dimensions. We use a variant of the proper time method supplemented by a simple choice of cutoff function. We find that the dimensionless coefficient of the Chern-Simons term, , has vanishing beta function. The flow of the cosmological constant and Newton's constant depends on ; we study analytically the structure of the flow and its fixed points in the limits of small and large .
