Title: Elliptic equations with one-sided critical growth Authors: Marta Calanchi (Univ. degli Studi,Milano, Italy) Bernhard Ruf (Univ. degli Studi,Milano, Italy) Abstract: We consider elliptic equations in bounded domains $\Omega\subset \mathbb{R}^N $ with nonlinearities which have critical growth at $+\infty$ and linear growth $\lambda$ at $-\infty$, with $\lambda > \lambda_1$, the first eigenvalue of the Laplacian. We prove that such equations have at least two solutions for certain forcing terms provided $N \ge 6$. In dimensions $N = 3,4,5$ an additional lower order growth term has to be added to the nonlinearity, similarly as in the famous result of Brezis-Nirenberg for equations with critical growth.
