Nonlinear Galerkin method in the finite difference case and wavelet-like incremental unknowns

SummaryThe IMG algorithm (Inertial Manifold-Multigrid algorithm) which uses the first-order incremental unknowns was introduced in [20]. The IMG algorithm is aimed at numerically implementing… Expand

In this paper we show that one can use a fixed nontrivial Möbius transformation as a test map to test the discreteness of a nonelementary Möbius group. We also establish two theorems in algebraic… Expand

This paper studies traveling-wave solutions of the partial differential equations which model waves in a horizontal water channel traveling in both directions. The existence of solitary-wave… Expand

Incremental unknowns for solving partial differential equations

SummaryIncremental unknowns have been proposed in [T] as a method to approximate fractal attractors by using finite difference approximations of evolution equations. In the case of linear elliptic… Expand

Incremental unknowns in finite differences: condition number of the matrix

The utilization of incremental unknowns (IU) with multilevel finite differences was proposed in [R. Temam, SIAM J. Math. Anal., 21 (1991), pp. 154–178] for the integration of elliptic partial… Expand
