A Priori Estimates and Existence Results for Some Semilinear Elliptic Problems.

Abstract

Problems arising in, for example, physics, biology and chemical reactors lead to boundary value problems for semilinear elliptic equations. The question of identifying for which nonlinearities these semilinear problems have solutions is by no means settled. Roughly speaking, nonlinearities which grow too rapidly yield unsolvable problems while under other conditions on the growth existence can be proved. Here we improve some conditions which were previously known to guarantee the existence of positive solutions of such problems.
