Linear stochastic differential equations in the dual of a multi-Hilbertian space

Abstract

We prove the existence and uniqueness of strong solutions for linear stochastic differential equations in the space dual to a multi–Hilbertian space driven by a finite dimensional Brownian motion under relaxed assumptions on the coefficients. As an application, we consider equtions in S' with coefficients which are differential operators violating the typical growth and monotonicity conditions.
