Construction of a Radial Solution to a Superlinear Dirichlet Problem that Changes Sign Exactly Once
We provide a method for finding a radial solution to a superlinear Dirichlet problem in a ball that changes sign exactly once and implement it using mathematical software. As a by-product, we conclude that the least energy sign changing solution for that problem is nonradial, which has been proved using different methods in  and
