Relative Decay Conditions on Liouville Type Theorem for the Steady Navier–Stokes System
نویسندگان
چکیده
In this paper we prove Liouville type theorem for the stationary Navier–Stokes equations in \(\mathbb {R}^3\) under assumptions on relative decays of velocity, pressure and head pressure. More precisely, show that any smooth solution (u, p) satisfying \(u(x) \rightarrow 0\) as \(|x|\rightarrow +\infty \) condition finite Dirichlet integral \(\int _{\mathbb {R}^3} | \nabla u|^2 dx <+\infty is trivial, if either \(|u(x)|/|Q(x)|=O(1)\) or \(|p(x)|/|Q(x)| =O(1) \infty \), where \(|Q|=\frac{1}{2} |u|^2 +p\)

A Liouville Type Theorem for an Integral System
In this paper, we study a conjecture of J.Serrin and give a partial generalized result of the work of de Figueiredo and Felmer about Liouville type Theorem for non-negative solutions for an elliptic system. We use a new type of moving plane method introduced by Chen-Li-Ou. Our new ingredient is the use of Stein-Weiss inequality.
متن کاملA Liouville-type theorem for Schrödinger operators
In this paper we prove a sufficient condition, in terms of the behavior of a ground state of a symmetric critical operator P1, such that a nonzero subsolution of a symmetric nonnegative operator P0 is a ground state. Particularly, if Pj := −∆ + Vj , for j = 0, 1, are two nonnegative Schrödinger operators defined on Ω ⊆ R such that P1 is critical in Ω with a ground state φ, the function ψ 0 is a...
متن کاملA Liouville-type theorem and the decay of radial solutions of a semilinear heat equation
We consider the semilinear parabolic equation ut = ∆u+ up on RN , where the power nonlinearity is subcritical. We first address the question of existence of entire solutions, that is, solutions defined for all x ∈ RN and t ∈ R. Our main result asserts that there are no positive radially symmetric bounded entire solutions. Then we consider radial solutions of the Cauchy problem. We show that if ...
متن کاملA Liouville type theorem for a class of anisotropic equations
In this paper we are dealing with entire solutions of a general class of anisotropic equations. Under some appropriate conditions on the data, we show that the corresponding equations cannot have non-trivial positive solutions bounded from above.
