On semilinear elliptic equations with indefinite nonlinearities [PDF]

open access: possibleCalculus of Variations and Partial Differential Equations, 1993
Abstract: "This paper concerns semilinear elliptic equations whose nonlinear term has the form W(x)f(u) where W changes sign. We study the existence of positive solutions and their multiplicity. The important role played by the negative part of W is contained in a condition which is shown to be necessary for homogeneous f.

Symmetrization for singular semilinear elliptic equations

Annali di Matematica Pura ed Applicata, 2012
In this paper, we prove some comparison results for the solution to a Dirichlet problem associated with a singular elliptic equation and we study how the summability of such a solution varies depending on the summability of the datum f.

On some Semilinear Elliptic Equations

AIP Conference Proceedings, 2009
In this paper we study the third type boundary value problem for a Semilinear Elliptic Equation. Here the existence of the weak solution for the considered problem is proved and also the uniqueness of the solution of the considered problem, in a model case, is proved.
