SPINNING BLACK-HOLES IN (2-DIMENSIONAL STRING AND DILATON GRAVITY(1))

We present a new class of spinning black hole solutions in (2 + 1)-dim ensional general relativity minimally coupled to a dilaton with potent ial e(b phi)Lambda. When b = 4, the corresponding spinning black hole is a solution of low energy (2 + 1)-dimensional string gravity. Apart from the limiting case of the BTZ black hole, these spinning black hol es have no inner horizon and a curvature singularity only at the origi n. We compute the mass and angular momentum parameters of the solution s at spatial infinity, as well as their temperature and entropy.
