Multiple solutions for some Neumann-Steklov boundary value problems with ψ-laplacian
Author(s): Konan Charles Etienne Goli and David Paul Tuo
Abstract: We study the existence of multiple solutions of the quasilinear equation (ψ(u'(t)))'= f(t,u(t),u'(t)),t∈[0,T] submitted to nonlinear Neumann-Steklov boundary conditions, where ψ:]-a,a[→R, with 0<a < +∞, is an increasing homeomorphism such that ψ(0)=0. Combining some sign conditions and lower and upper solutions method, we obtain existence of two or three solutions.
