摘要
We consider a nonlinear eigenvalue problem for the Dirichlet (p, q)-Laplacian with a sign-changing Caratheodory reaction. Using variational tools, truncation and comparison techniques, and critical groups, we prove an existence and multiplicity result which is global in the parameter lambda > 0(bifurcation-type theorem). Our work here complements the recent one by Papageorgiou-Qin-Radulescu, Bull. Sci. Math. 172 (2021).
