# Existence for nonlinear finite dimensional stochastic differential equations of subgradient type

• One proves via variational techniques the existence and uniqueness of a strong solution to the stochastic differential equation $dX+{\partial} {\varphi} (t,X)dt\ni \sum\limits^N_{i = 1}σ_i(X)d{β}_i,\ X(0) = x,$ where ${\partial}{\varphi} :{\mathbb{R}}^d\to2^{{\mathbb{R}}^d}$ is the subdifferential of a convex function ${\varphi}:{\mathbb{R}}^d\to{\mathbb{R}}$ and $σ_i∈ L({\mathbb{R}}^d,{\mathbb{R}}^d)$, $1≤ d<{∞}$.
