Abstract
We study risk-sensitive ergodic control problem for controlled diffusion processes in the non-negative orthant. We consider ergodic cost evaluation criteria. Under certain assumptions we first establish the existence of a solution of the corresponding HJB equation. In addition we completely characterize the optimal control in the space of stationary Markov controls.
