Sing-changing solutions for nonlinear problems with strong resonance
Electronic journal of differential equations, Tome 2012 (2012)
Using critical point theory and index theory, we prove the existence and multiplicity of sign-changing solutions for some elliptic problems with strong resonance at infinity, under weaker conditions than in the references.
