“…Nonlinear differential equations arise in many fields of sciences ( such as physics, mechanics, and material science), and have been studied by many authors in the last decades (see [1,2,3,4,5,6,7,8,9,10,11,12,13,14] and the references therein). Differential inclusions governed by subdifferential, which was first studied by Brezis in [1], play an important role in the theory of the nonlinear evolution equations (see [1,2,3,4,5,6,7]).…”
