具有不定位势项的非线性奇异问题

Nonlinear singular problems with indefinite potential term

Nikolaos S. Papageorgiou, Vicenţiu D. Rădulescu, Dušan D. Repovš

摘要:

考虑由非齐次微分算子和不定位势驱动的非线性Dirichlet问题。在反应中,我们有一个奇异项和凹凸非线性的竞争效果。在本文中,凹项是参数的。我们证明了一个描述正解集随正参数$λ$变化的分支定理。本工作继续我们在arXiv:2004.12583中发表的研究,其中$ξ\equiv 0 $和反应中的参数项是奇异项。

英文摘要:

We consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator plus an indefinite potential. In the reaction we have the competing effects of a singular term and of concave and convex nonlinearities. In this paper the concave term is parametric. We prove a bifurcation-type theorem describing the changes in the set of positive solutions as the positive parameter $λ$ varies. This work continues our research published in arXiv:2004.12583, where $ξ\equiv 0 $ and in the reaction the parametric term is the singular one.
