Title: Local superlinearity and sublinearity for indefinite semilinear elliptic problems
Author: De Figueiredo, DG
Gossez, JP
Ubilla, P
Abstract: In this paper the usual notions of superlinearity and sublinearity for semilinear problems like -Deltau =f (x, u) are given a local form and extended to indefinite nonlinearities. Here f (x, s) is allowed to change sign or to vanish for s near zero as well as for s near infinity. Some of the well-known results of Ambrosetti-Brezis-Cerami are partially extended to this context.
