A Carleman-based numerical method for quasilinear elliptic equations with over-determined boundary data and applications

نویسندگان

چکیده

We propose a new iterative scheme to compute the numerical solution an over-determined boundary value problem for general quasilinear elliptic PDE. The main idea is repeatedly solve its linearization by using quasi-reversibility method with suitable Carleman weight function. presence of function allows us employ estimate prove convergence sequence generated above desired solution. iteration fast at exponential rate without need initial good guess. apply this solutions some equations and large class first-order Hamilton-Jacobi equations. Numerical results are presented.

On Neumann Boundary Value Problems for Some Quasilinear Elliptic Equations

We study the role played by the indefinite weight function a(x) on the existence of positive solutions to the problem  −div (|∇u|∇u) = λa(x)|u|u+ b(x)|u|u, x ∈ Ω, ∂u ∂n = 0, x ∈ ∂Ω , where Ω is a smooth bounded domain in Rn, b changes sign, 1 < p < N , 1 < γ < Np/(N − p) and γ 6= p. We prove that (i) if ∫ Ω a(x) dx 6= 0 and b satisfies another integral condition, then there exists some λ∗ suc...

Nonlinear Neumann Boundary Conditions for Quasilinear Degenerate Elliptic Equations and Applications

We prove comparison results between viscosity sub and supersolutions of degenerate elliptic and parabolic equations associated to, possibly non-linear, Neumann boundary conditions. These results are obtained under more general assumptions on the equation (in particular the dependence in the gradient of the solution) and they allow applications to quasilinear, possibly singular, elliptic or para...

A method based on the meshless approach for singularly perturbed differential-difference equations with Boundary layers

In this paper, an effective procedure based on coordinate stretching and radial basis functions (RBFs) collocation method is applied to solve singularly perturbed differential-difference equations with layer behavior. It is well known that if the boundary layer is very small, for good resolution of the numerical solution at least one of the collocation points must lie in the boundary layer. In ...

Analytic solutions for the Stephen's inverse problem with local boundary conditions including Elliptic and hyperbolic equations

In this paper, two inverse problems of Stephen kind with local (Dirichlet) boundary conditions are investigated. In the first problem only a part of boundary is unknown and in the second problem, the whole of boundary is unknown. For the both of problems, at first, analytic expressions for unknown boundary are presented, then by using these analytic expressions for unknown boundaries and bounda...

Existence of Solutions for Quasilinear Elliptic Equations with Nonlinear Boundary Conditions and Indefinite Weight

In this article, we establish the existence and non-existence of solutions for quasilinear equations with nonlinear boundary conditions and indefinite weight. Our proofs are based on variational methods and their geometrical features. In addition, we prove that all the weak solutions are in C1,β(Ω) for some β ∈ (0, 1).
