We consider a nonlinear Robin problem driven by the sum of p-Laplacian and q-Laplacian (i.e. the (p,q)-equation). In the reaction there are competing effects of a singular term and a parametric perturbation λf(z,x), which is Carathéodory and (p1)-superlinear at xR, without satisfying the Ambrosetti–Rabinowitz condition. Using variational tools, together with truncation and comparison techniques, we prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter λ>0 varies.

具有奇异和超线性项的Robin双相问题

我们考虑由 p-拉普拉斯和 q-拉普拉斯(即 pq-方程)。在反应中,存在奇异项和参数扰动的竞争效应λFžX,这是Carathéodory和 p-1个-超线性 X[R不满足Ambrosetti–Rabinowitz条件。使用变分工具,结合截断和比较技术,我们证明了分叉型结果,该结果描述了一组正解的变化作为参数λ>0 不同。
