Nonlinear second order evolution inclusions with noncoercive viscosity term

In this paper we deal with a second order nonlinear evolution inclusion, with a nonmonotone, noncoercive viscosity term. Using a parabolic regularization (approximation) of the problem and a prioribounds that permit passing to the limit, we prove that the problem has a solution. (C) 2017 Elsevier Inc.
