The Lazer Mckenna Conjecture for Radial Solutions in the R(N) Ball
MetadataShow full metadata
When the range of the derivative of the nonlinearity contains the first k eigenvalues of the linear part and a certain parameter is large, we establish the existence of 2k radial solutions to a semilinear boundary value problem. This proves the Lazer McKenna conjecture for radial solutions. Our results supplement those in , where the existence of k + 1 solutions were proven.
