In this paper we extend some of the results of the authorson stochastic differential gamesto the case of risk sensitive payoffs.

The existence of solutions of the Cauchy problem for (overdetermined) systems of linear partial differential operators with constant coefficients in some classes of functions or distributions is equivalent to the validity of Phragmen-Lindelöf-type princip... see more

A simple  exit time problem with degenerate cos is here considered. Using a new technique for constructing admissible trajectories, a semiconcavity result for the value function ? is obtained. Such a property of ? is then applied to obtain optimality... see more

A short survey of recent results on smoothness of weak solutions to parabolic systems with nonsmooth coefficients in olane is given. Moreover, for space dimensions n\ge 3 and any closed subset F in R^n we construct a linear parabolic system with bounded m... see more

We extend some result of [2] proving the continuity of bounded solutions of the singular equation  (ß(u))_t=Lu where L is a more general operator of second order.
