Uniqueness and a Priori Estimates

چکیده
Under some conditions on f(u), we show that for small, the only solutions to the following elliptic equation u ? u + f(u) = 0 in ; u > 0 in ; @u @ = 0 on @ are constants, provided that R 3 is convex. The proof only uses integration by parts.

Existence and uniqueness of weak solutions for a class of nonlinear divergence type diffusion equations
In this paper, we study the Neumann boundary value problem of a class of nonlinear divergence type diffusion equations. By a priori estimates, difference and variation techniques, we establish the existence and uniqueness of weak solutions of this problem.
متن کاملA priori estimates for excitable models
The reaction-diffusion system of Fitzhugh Nagumo is considered. The initialboundary problems with Neumann and Dirichlet conditions are analyzed. By means of an equivalent semilinear integrodifferential equation which characterizes several dissipative models of viscoelasticity, biology, and superconductivity, some results on existence, uniqueness and a priori estimates are deduced both in the li...
متن کاملNew effective moduli of uniqueness and uniform a–priori estimates for constants of strong unicity by logical analysis of known proofs in best approximation theory
Let U and V be complete separable metric spaces, Vu compact in V and G : U × V → IR a continuous function. For a large class of (usually non–constructive) proofs of uniqueness theorems ∧ u ∈ U, v1, v2 ∈ Vu ( G(u, v1) = inf v∈Vu G(u, v) = G(u, v2) → v1 = v2 ) one can extract an effective modulus of uniqueness Φ by logical analysis, i.e. ∧ u ∈ U, v1, v2 ∈ Vu, n ∈ IN ( 2 ∧ i=1 ( G(u, vi)− inf v∈Vu...
متن کاملOptimal order finite element approximation for a hyperbolic integro-differential equation
Semidiscrete finite element approximation of a hyperbolic type integro-differential equation is studied. The model problem is treated as the wave equation which is perturbed with a memory term. Stability estimates are obtained for a slightly more general problem. These, based on energy method, are used to prove optimal order a priori error estimates.
متن کاملOn the Oblique Boundary Value Problems for Monge-ampère Equations
(1.3) β(x) · ν(x) > 0, φu(x, u) ≤ −γ0(x) < 0. Here ν is the unit outer normal to ∂Ω, γ0 is a positive function on ∂Ω, and Dβ = β · ∇. The existence and uniqueness of the classical convex solution of the equations (1.1) and (1.2) under some suitiable conditions on f, φ and ν was studied by P.L. Lions, N. Trudinger and J. Urbas [9]. They applied the method of continuity plus a priori estimates to...
