In this paper we study the Existence and Uniqueness of solutions for the following Cauchy problem:where and are bounded linear operators in a Hilbert space , is a family of self-adjoint operators, is a non-linear map on and is a function from with values in .
As an application of problem (1) we consider the following Cauchy problem:where is a cylindrical domain in ; and are bounded functions defined in an open bounded set ,where and are bounded functions on and is a function from with values in .
