Introduction In this paper we deal with the existence and a variational of constant formula for solutions of a parabolic hemivariational inequality of the form u x t x t - div C e u x t E x t f x t in Q X 0 to u x t 0 on r1 X 0 to C e u x t v - v u x t on r0 X 0 to E x t e y u x t . x t Q X 0 to u x 0 u0 x in Q where Q is a bounded domain in RN with sufficiently smooth boundary r.
