Abstract

We consider a nonlinear parametric Dirichlet problem driven by the p-Laplace differential operator and a reaction which has the competing effects of a parametric singular term and of a Carathéodory perturbation which is ($$p-1$$p-1)-linear near $$+\infty $$+∞. The problem is uniformly nonresonant with respect to the principal eigenvalue of $$(-\Delta _p,W^{1,p}_0(\Omega ))$$(-Δp,W01,p(Ω)). We look for positive solutions and prove a bifurcation-type theorem describing in an exact way the dependence of the set of positive solutions on the parameter $$\lambda >0$$λ>0.

非线性参数奇异狄利克雷问题的正解

我们考虑了一个由p-拉普拉斯微分算子驱动的非线性参数Dirichlet问题和一个在$$+\infty $$ +∞附近具有参数奇异项和($$p-1$$ p-1)-线性的carathacimodory摄动的竞争效应的反应。该问题相对于$$(-\Delta _p,W^{1,p}_0(\Omega ))$$ (-Δp,W01,p(Ω))的主特征值是一致非共振的。我们寻找正解并证明了一个分岔型定理，该定理精确地描述了正解集对参数$$\lambda >0$$ λ>0的依赖关系。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
