In this article, we investigate a class of nonlinear elliptic equations driven by the p-Laplacian operator in the entire space RN, known as the Emden-Fowler equation type. The complexity of the problem arises from the interplay of two distinct critical growth phenomena, characterized by both Sobolev and Hardy senses. We explore the existence of positive radial solutions, with the proof relying on variational methods. Due to multiple critical nonlinearities, the Mountain Pass Lemma does not yield critical points but only Palais-Smale sequences. The primary challenge lies in the asymptotic competition among the energies carried by these multiple critical nonlinearities.
在本文中,我们研究了一类由整个 RN 空间中的 p-Laplacian 算子驱动的非线性椭圆方程,即 Emden-Fowler 方程类型。问题的复杂性源于两种截然不同的临界增长现象的相互作用,这两种现象同时具有 Sobolev 和 Hardy 意义上的特征。我们探讨了正径向解的存在性,其证明依赖于变分法。由于存在多个临界非线性,山口定理并不能得到临界点,而只能得到 Palais-Smale 序列。主要挑战在于这些多重临界非线性所携带的能量之间的渐近竞争。

Global classical solutions of free boundary problem of compressible Navier–Stokes equations with degenerate viscosity 具有退化粘度的可压缩纳维-斯托克斯方程自由边界问题的全局经典解

This paper concerns with the one dimensional compressible isentropic Navier–Stokes equations with a free boundary separating fluid and vacuum when the viscosity coefficient depends on the density. Precisely, the pressure P and the viscosity coefficient μ are assumed to be proportional to ργ and ρθ respectively, where ρ is the density, and γ and θ are constants. We establish the unique solvability in the framework of global classical solutions for this problem when γθ>1. Since the previous results on this topic are limited to the case when θ(0,1], the result in this paper fills in the gap for θ>1. Note that the key estimate is to show that the density has a positive lower bound and the new ingredient of the proof relies on the study of the quasilinear parabolic equation for the viscosity coefficient by reducing the nonlocal terms in order to apply the comparison principle.
本文涉及一维可压缩等熵 Navier-Stokes 方程,该方程的自由边界将流体和真空隔开,此时粘度系数取决于密度。确切地说,假设压力 P 和粘度系数 μ 分别与 ργ 和 ρθ 成比例,其中 ρ 是密度,γ 和 θ 是常数。我们在全局经典解的框架内建立了当γ≥θ>1 时该问题的唯一可解性。 由于之前有关该主题的结果仅限于θ∈(0,1]的情况,本文的结果填补了θ>1 的空白。需要注意的是,关键的估计是证明密度有一个正下限,而证明的新内容依赖于对粘性系数的准线性抛物方程的研究,通过减少非局部项来应用比较原理。

We consider the initial boundary value problem for the compressible fluid-particle interaction system with cylindrical symmetry. We derive explicit Prandtl type boundary layer equations and prove the global in time stability of the boundary layer profile together with the optimal convergence rate when the shear viscosity μ=κρβ goes to zero without any smallness assumption on the initial and boundary data.

Clifford analysis offers suited framework for a unified treatment of higher-dimensional phenomena. This paper is concerned with boundary value problems for higher order Dirac operators, which are directly related to the Lamé-Navier and iterated Laplace operators.

We consider a class of first-order partial differential operators, acting on the space of ultradifferentiable periodic functions, and we describe their range by using the following conditions on the coefficients of the operators: the connectedness of certain sublevel sets, the dimension of the subspace generated by the imaginary part of the coefficients, and Diophantine conditions. In addition, we show that these properties are also linked to the regularity of the solutions. The results extend previous ones in Gevrey classes.

We consider the motion of an incompressible viscous fluid on a compact Riemannian manifold M with boundary. The motion on M is modeled by the incompressible Navier-Stokes equations, and the fluid is subject to pure or partial slip boundary conditions of Navier type on M. We establish existence and uniqueness of strong as well as weak (variational) solutions for initial data in critical spaces. Moreover, we show that the set of equilibria consists of Killing vector fields on M that satisfy corresponding boundary conditions, and we prove that all equilibria are (locally) stable. In case M is two-dimensional we show that solutions with divergence free initial condition in L2(M;TM) exist globally and converge to an equilibrium exponentially fast.

This paper is concerned with curved fronts for Belousov-Zhabotinskii reaction-diffusion system in external domains Ω=RNK with a compact obstacle K and aims to investigate the large time dynamics of an entire solution emanating from a pyramidal traveling wave. By constructing several super- and sub-solutions with desirable characteristics, some favorable properties of the pyramidal traveling wave are obtained. We show that by providing propagation completely of the entire solution, the pyramidal traveling wave will converge to the same shape of the pyramidal traveling wave after far behind the obstacle.

We consider the boundary problem(1)(r(x)y(x))+q(x)y(x)=f(x),xR,(2)lim|x|y(x)=0 under the following conditions:
  • 1)
    r>0,1rL1loc(R),qL1loc(R);
  • 2)
    equation (1) is correctly solvable in Lp(R), p(1,).
We obtain necessary and sufficient requirements for the functions r and q under which, regardless of the choice of a function fLp(R), p(1,), the solution yLp(R) of equation (1) satisfies (2).
我们考虑以下条件下的边界问题(1)-(r(x)y′(x))′+q(x)y(x)=f(x),x∈R,(2)lim|x|→∞y(x)=0:1)r>0,1r∈L1loc(R),q∈L1loc(R);2)equation (1) is correctly solvable in Lp(R), p∈(1,∞).我们得到了函数 r 和 q 的必要条件和充分条件,在这些条件下,无论选择哪个函数 f∈Lp(R),p∈(1,∞),方程 (1) 的解 y∈Lp(R) 都满足 (2)。
