Abstract
In this paper, we study elliptic equations of the form (Formula presented.) where (Formula presented.) is the logarithmic double phase operator given by (Formula presented.) (Formula presented.) is Euler's number, (Formula presented.), (Formula presented.), is a bounded domain with Lipschitz boundary (Formula presented.), (Formula presented.), (Formula presented.) with (Formula presented.), (Formula presented.) and (Formula presented.). Under mild assumptions on the nonlinearity (Formula presented.) we prove multiplicity results for the problem above and get two constant sign solutions and another third nontrivial solution. This third solution is obtained by using the theory of critical groups. As a result of independent interest, we show that every weak solution of the problem above is essentially bounded.
