Numerical Solution of Two-dimensional Diierential Games

On Differential Games for Infinite-dimensional Systems with Nonlinear, Unbounded Operators

We consider a two-player, zero-sum diierential game governed by an abstract nonlinear diierential equation of accretive type in an innnite dimensional space. We prove that the value function of the game is the unique viscosity solution of the corresponding Hamilton-Jacobi-Isaacs equation in the sense of Crandall-Lions 12]. We also discuss some properties of this notion of solution.

Fast numerical methods for total variation minimization in image reconstruction

We apply a total variation minimization technique for the deblurring of two-dimensional images. This yields an integro-diierential equation with a nonlinear elliptic partial diierential operator. In this paper we discuss a numerical scheme for the eecient solution of this integro-diierential equation. Results are presented for a deconvolution problem arising in ground-based astronomical imaging.

Numerical solution of a class of nonlinear two-dimensional integral equations using Bernoulli polynomials

In this study, the Bernoulli polynomials are used to obtain an approximate solution of a class of nonlinear two-dimensional integral equations.
