Abstract

We consider a parametric double phase Dirichlet problem. Using variational tools together with suitable truncation and comparison techniques, we show that for all parametric values λ > λ- the problem has at least three nontrivial solutions, two of which have constant sign. Also, we identify the critical parameter λ precisely in terms of the spectrum of the q-Laplacian.
