Weak solutions for a fractional equation in R^n with Kirchhoff terms

We explore the multiplicity of weak solutions to a nonlocal equation in R^n governed by a fractional power of the p-Laplacian combined with a Kirchhoff-type term. The nonlinearity involves two real parameters, one of which is of perturbing nature, and can overpower the critical fractional exponent. Our arguments rely upon the variational apparatus; the lack of compactness of the Sobolev embeddings is circumvented by the use of convenient weight functions.
