考虑非齐次方程-Δpu-Δqu=α的Dirichlet问题|u| p-2u+β| u| q-2u+f(x),其中,和为参数.我们探讨假设和保证所考虑的问题的可解决性。此外,我们引入了几个曲线上的平面分配的参数集的问题有或没有积极的或符号变化的解决方案,providedfis的一个常数符号。
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.
