Positive solutions for superdiffusive mixed problems
arXiv:1711.01884 · doi:10.1016/j.aml.2017.09.017
Abstract
We study a semilinear parametric elliptic equation with superdiffusive reaction and mixed boundary conditions. Using variational methods, together with suitable truncation techniques, we prove a bifurcation-type theorem describing the nonexistence, existence and multiplicity of positive solutions.
