The double phase Dirichlet problem when the lowest exponent is equal to 1

In this paper we prove an existence and uniqueness result for the double phase Dirichlet problem when lowest exponent is equal to 1. Our solution a function of bounded variation that simultaneously lies in suitable weighted Sobolev space found as limit sequence solutions intermediate problems whose $p$ goes As that, our approach involves study some relevant properties generalized Orlicz-Sobolev spaces.
