摘要

摘要建立了一类半线性非局部Neumann问题非负解的先验$$L^\infty $$ L∞估计。根据这些估计,在适当的扩散系数和非线性假设下,我们得到了非常解的不存在性。此外,我们证明了在可能的超临界非线性情况下径向非递减解的存在性结果,并推广到$$0<s\le 1/2$$ 0 &lt;S≤1 / 2,从[7]开始分析。

Existence and non-existence results for a semilinear fractional Neumann problem
Abstract We establish a priori $$L^\infty $$ L -estimates for non-negative solutions of a semilinear nonlocal Neumann problem. As a consequence of these estimates, we get non-existence of non-constant solutions under suitable assumptions on the diffusion coefficient and on the nonlinearity. Moreover, we prove an existence result for radial, radially non-decreasing solutions in the case of a possible supercritical nonlinearity, extending to the case $$0 0 < s 1 / 2 the analysis started in [7].

期刊介绍: Nonlinear Differential Equations and Applications (NoDEA) provides a forum for research contributions on nonlinear differential equations motivated by application to applied sciences. The research areas of interest for NoDEA include, but are not limited to: deterministic and stochastic ordinary and partial differential equations, finite and infinite-dimensional dynamical systems, qualitative analysis of solutions, variational, topological and viscosity methods, mathematical control theory, complex dynamics and pattern formation, approximation and numerical aspects.
