Three symmetric solutions for a class of elliptic equations involving the \(p\)-Laplacian with discontinuous nonlinearities in \(\mathbb R^{N}\)
The authors establish radially symmetric solutions for a class of elliptic equations involving the \(p\)-Laplacian with discontinuous nonlinearities in the whole space. To this end, they use a non-smooth version of the Ricceri three critical points theorem.
