Infinitely many radial solutions for a sub-super critical Dirichlet boundary value problem in a ball

Alfonso Castro, John Kwon, Chee Meng Tan

Abstract:
We prove the existence of infinitely many solutions to a semilinear Dirichlet boundary value problem in a ball for a nonlinearity $g(u)$ that grows subcritically for $u$ positive and supercritically for $u$ negative.
