Supercritical problems with concave and convex nonlinearities in \(\mathbb{R}^N\). (English) Zbl 1472.35192

Summary: In this paper, by utilizing a newly established variational principle on convex sets, we provide an existence and multiplicity result for a class of semilinear elliptic problems defined on the whole \(\mathbb{R}^N\) with nonlinearities involving linear and superlinear terms. We shall impose no growth restriction on the nonlinear term, and consequently, our problem can be supercritical in the sense of the Sobolev embeddings.
