<p style='text-indent:20px;'>In this paper, we consider a mixed boundary value problem with a double phase partial differential operator, an obstacle effect and a multivalued reaction convection term. Under very general assumptions, an existence theorem for the mixed boundary value problem under consideration is proved by using a surjectivity theorem for multivalued pseudomonotone operators together with the approximation method of Moreau-Yosida. Then, we introduce a family of the approximating…

We study elliptic problems where the boundedness condition is “separated” from the coercivity condition, which leads to the loss of uniqueness, regularity, and some other properties of solutions. We
