## Stationary variational inequalities.

n the context of the section ( Optimal stopping time problem ) we consider the state process The functions are independent of time and . It follows from the considerations of the sections ( Representation of solution for elliptic PDE using stochastic process ) and ( Optimal stopping time problem ) that the PDE of the problem is of the elliptic type.
