In this work we study the existence of positive solution to the fractional quasilinear problem, (Δ)su=λu|x|2s+|u|p+μf in Ω,u>0 in Ω,u=0 in (RNΩ),where Ω is a C1,1 bounded domain in RN, N>2s,μ>0, 12<s<1, and 0<λ<ΛN,s is defined in (3). We assume that f is a non-negative function with additional hypotheses. As we will see, there are deep differences with respect to the case λ=0. More precisely,

If λ>0, there exists a critical exponent p+(λ,s) such that for p>p+(λ,s) there is no positive solution.

Moreover, p+(λ,s) is optimal in the sense that, if p<p+(λ,s) there exists a positive solution for suitable data and μ sufficiently small.

相对于Hardy势梯度具有临界增长的分数阶KPZ方程

在这项工作中,我们研究了分数拟线性问题的正解的存在, -Δsü=λü|X|2s+|ü|p+μF 在 Ωü>0 在 Ωü=0 在 [RñΩ哪里 Ω 是一个 C1个1个 有界域 [Rññ>2sμ>01个2<s<1个0<λ<Λñs在(3)中定义。我们假设F是带有其他假设的非负函数。正如我们将看到的,此案有很大的不同λ=0。更确切地说,

如果 λ>0,存在一个关键指数 p+λs 这样 p>p+λs 没有积极的解决方案。

此外, p+λs 在某种意义上说是最佳的 p<p+λs 对于合适的数据存在一个积极的解决方案, μ 足够小。
