We consider the Dirichlet problem for the nonhomogeneous equation -Δpu-Δqu=α|u|p-2u+β|u|q-2u+f(x) in a bounded domain, where, andare parameters. We explore assumptions onandthat guarantee the resolvability of the considered problem. Moreover, we introduce several curves on the-plane allocating sets of parameters for which the problem has or does not have positive or sign-changing solutions, providedfis of a constant sign.
