Controlled diffusion processes on infinite horizon with the overtaking criterion

The optimal control of diffusion processes on the infinite time interval are studied. All the costs diverge to infinity and we employ the overtaking criterion, as well as considering minimal growth rate controls. The Bellman equation for the problem is considered and its solution is given an interpretation connected with the overtaking optimality notion. Control problems with a cost including a generalized discount factor (which is not integrable on [(, ∞)) are also studied. Both cases, where the diffusion is inRn or where it is reflected from the boundary of a bounded set, are considered.
