Abstract In this article, we study the existence of ground state solutions for the Schrödinger-Poisson-Slater type equation with the Coulomb-Sobolev critical growth: − Δ u + 1 4 π ∣ x ∣ ∗ ∣ u ∣ 2 u = ∣ u ∣ u + μ ∣ u ∣ p − 2 u , in R 3 , -Delta u+left(frac{1}{4pi | x| }ast | u{| }^{2}right)u=| u| u+mu | u{| }^{p-2}u,hspace{1.0em}{rm{in}}hspace{0.33em}{{mathbb{R}}}^{3}, where μ > 0 mu gt 0 and 3 < p < 6 3lt plt 6 . With the help of the Nehari-Pohozaev method, we obtain a ground-state solution for the above equation by employing compactness arguments.

Abstract The article deals with the existence of a pair of nontrivial nonnegative and nonpositive solutions for a nonlinear weighted quasilinear equation in R N {{mathbb{R}}}^{N} , which involves a double-phase general variable exponent elliptic operator A {bf{A}} . More precisely, A {bf{A}} has behaviors like ∣ ξ ∣ q ( x ) − 2 ξ {| xi | }^{qleft(x)-2}xi if ∣ ξ ∣ | xi | is small and like ∣ ξ ∣ p ( x ) − 2 ξ {| xi | }^{pleft(x)-2}xi if ∣ ξ ∣ | xi | is large. Existence is proved by the Cerami condition instead of the classical Palais-Smale condition, so that the nonlinear term f ( x , u ) fleft(x,u) does not necessarily have to satisfy the Ambrosetti-Rabinowitz condition.
摘要本文讨论了R N｛mathbb｛R｝｝^｛N｝中一个非线性加权拟线性方程的一对非平凡非负和非正解的存在性，该方程涉及一个双相广义变指数椭圆算子a｛bf｛a｝。更准确地说，A｛bf｛A｝｝具有类似于如果Şξ|nenenebc xi |很小则Şξ。用Cerami条件而不是经典的Palais-Smale条件证明了存在性，使得非线性项f（x，u）fleft（x，u）不一定满足Ambrosetti-Rabinowitz条件。

Abstract In this article, we develop a continuous periodic switching model depicting Wolbachia infection frequency dynamics in mosquito populations by releasing Wolbachia-infected mosquitoes, which is different from the discrete modeling efforts in the literature. We obtain sufficient conditions on the existence of a unique and exactly two periodic solutions and analyze the stability of each periodic solution, respectively. We also provide a brief discussion and several numerical examples to illustrate our theoretical results.

By applying the penalization approach together with the Nehari manifold approach in the studies of Szulkin and Weth, we obtain the existence of an infinite sequence of localized solutions of higher topological type. In addition, we also give a concrete set as the concentration position of these localized solutions. It is noted that, in our main results, f f only belongs to C ( R , R ) Cleft({mathbb{R}},{mathbb{R}}) and does not satisfy the Ambrosetti-Rabinowitz-type condition.

Abstract We consider the nonlinear elliptic–parabolic boundary value problem involving the Dirichlet-to-Neumann operator of p-Laplace type at the critical Sobolev exponent. We first obtain the existence and asymptotic estimates of the global solution, and the sufficient conditions of finite time blowup of the solution by using the energy method. Second, we improve the regularity of solution by Moser-type iteration. Finally, we analyze the long-time asymptotic behavior of the global solution. Moreover, with the help of the concentration compactness principle, we present a precise description of the concentration phenomenon of the solution in the forward time infinity.

Abstract This article is concerned with the study of the initial value problem for the three-dimensional viscous Boussinesq system in the thin domain Ω ≔ R 2 × ( 0 , R ) Omega := {{mathbb{R}}}^{2}times left(0,R) . We construct a global finite energy Sobolev regularity solution ( v , ρ ) ∈ H s ( Ω ) × H s ( Ω ) left({bf{v}},rho )in {H}^{s}left(Omega )times {{mathbb{H}}}^{s}left(Omega ) with the small initial data in the Sobolev space H s + 2 ( Ω ) × H s + 2 ( Ω ) {H}^{s+2}left(Omega )times {{mathbb{H}}}^{s+2}left(Omega ) . Some features of this article are the following: (i) we do not require the initial data to be axisymmetric; (ii) the Sobolev exponent s s can be an arbitrary big positive integer; and (iii) the explicit asymptotic expansion formulas of Sobolev regular solution is given. The key point of the proof depends on the structure of the perturbation system by means of a suitable initial approximation function of the Nash-Moser iteration scheme.
