Multiple high‐energy solutions for an elliptic system with critical Hardy–Sobolev nonlinearity

This paper discusses the existence of multiple high‐energy solutions for a ‐Laplacian system involving critical Hardy‐Sobolev nonlinearity in . Considering that the “double” lack of compactness in the system is caused by the unboundedness of and the presence of the critical Hardy–Sobolev exponent, we demonstrate the version to of Struwe's classical global compactness result for double ‐Laplace operator. In virtue of the quantitative deformation lemma, a barycenter function, and the Brouwer degree theory, the existence of multiple high‐energy solutions is established. The results of this paper extend and complement the recent work.

Classification of positive solutions to [formula omitted]-Laplace equations with critical Hardy–Sobolev exponent

Let u∈D1,p(RN) be a positive solution to the critical equation −Δpu=upa∗−1|x|ain RN,where 1<p<N, 0<a<p and pa∗=(N−a)pN−p. By exploiting the method of moving planes, we show that u is radial and strictly radially decreasing about the origin. Consequently, u must have the form u(x)=(N−a)1pN−pp−1p−1pλλp+|x|p−ap−1N−pp−afor some λ>0.

Ground state solutions for Schrödinger–Poisson systems on ℝ3$$ {\mathbb{R}}&amp;#x0005E;3 $$ with a weighted critical exponent

In this paper, we are interested in the existence of ground state solutions for the weighted critical Schrödinger–Poisson systems. The weighted critical exponent may be the Hénon–Sobolev, the Sobolev or the Hardy–Sobolev critical exponent. Moreover, the potentials are power type, which may be singular at origin or unbounded. Due to the presence of Possion term, we can not directly obtain the boundedness of the Palais–Smale sequences of the associated functional for some cases. The Pohozaev identity, the minimax principle and some techniques are used to overcome the difficulties.

Infinitely many solutions for the fractional $p$&amp;$q$ problem with critical Sobolev-Hardy exponents and sign-changing weight functions

In this paper, we study the Kirchhoff type problems involving fractional $p$&$q$ problem with critical Sobolev-Hardy exponents and sign-changing weight functions. By using the fractional version of concentration-compactness principle together with Krasnoselskii's genus, we obtain the multiplicity of solutions for this kind problem. The main feature and difficulty of our equations arise in the fact that the Kirchhoff term $M$ could vanish at zero, that is, the problem is degenerate.

Multiplicity and asymptotic behavior of solutions to fractional (p,q)-Kirchhoff type problems with critical Sobolev-Hardy exponent

Let \(\Omega\subset\mathbb{R}^{N}\) be a bounded domain with smooth boundary and \(0\in\Omega\). For \(0&lt;s&lt;1\), \(1\le r&lt;q&lt;p\), \(0\le\alpha&lt;ps&lt;N\) and a positive parameter \(\lambda\), we consider the fractional \((p,q)\)-Laplacian problems involving a critical Sobolev-Hardy exponent. This model comes from a nonlocal problem of Kirchhoff type $$\displaylines{ \big(a+b[u]_{s,p}^{(\theta-1)p}\big)(-\Delta)_{p}^{s}u+(-\Delta)_{q}^{s}u =\frac{|u|^{p_{s}^{*}(\alpha)-2}u}{|x|^{\alpha}}+\lambda f(x)\frac{|u|^{r-2}u}{|x|^{c}}\quad \hbox{in }\Omega,\cr u=0\quad\text{in }\mathbb{R}^{N}\setminus\Omega, }$$ where \(a,b&gt;0\), \(c&lt;sr+N(1-r/p)\), \(\theta\in(1,p_{s}^{*}(\alpha)/p)\) and \(p_{s}^{*}(\alpha)\) is critical Sobolev-Hardy exponent. For a given suitable \(f(x)\), we prove that there are least two nontrivial solutions for small \(\lambda\), by way of the mountain pass theorem and Ekeland's variational principle. Furthermore, we prove that these two solutions converge to two solutions of the limiting problem as \(a\to 0^{+}\). For the limiting problem, we show the existence of infinitely many solutions, and the sequence tends to zero when \(\lambda\) belongs to a suitable range.
