In this paper, we consider a class of fractional Laplacian problems of the form: (Δ)p1(x,.)su+(Δ)p2(x,.)su+|u|q(x)2u=g(x)uγ(x)+λf(x,u)in Ω,u=0,on Ω, where ΩRN, (N2), is a bounded domain and (Δ)pi(x,.)s is the fractional pi(x,.)-Laplacian. We assume that λ is a nonnegative parameter and γ:Ω¯(0,1) is a continuous function. By using variational methods and monotonicity arguments combined with the theory of the generalized Lebesgue Sobolev spaces, we prove the existence of solutions to problem (Pλ).

具有可变指数和不定权重的奇异分数式拉普拉斯问题的解的存在性

在本文中,我们考虑以下形式的一类分数拉普拉斯问题: (-Δ)1(X,.)+(-Δ)2(X,.)+||q(X)-2=G(X)-γ(X)+λF(X,)在 Ω,=0, Ω, 在哪里 Ω电阻N, (N2), 是一个有界域并且 (-Δ)一世(X,.) 是小数 一世(X,.)- 拉普拉斯。我们假设λ是一个非负参数,并且γΩ¯(0,1)是连续函数。通过使用变分方法和单调性论证,结合广义 Lebesgue Sobolev 空间的理论,我们证明了问题的解的存在性(λ).
