摘要
In this article, the existence of a unique solution in the variational approach of the stochastic evolution equation dX(t) = F (X(t)) dt + G(X(t)) dL(t) driven by a cylindrical Levy process L is established. The coefficients F and G are assumed to satisfy the usual monotonicity and coercivity conditions. The noise is modelled by a cylindrical Levy processes which is assumed to belong to a certain subclass of cylindrical Levy processes and may not have finite moments.
