A quasi-projection approximation method applied to Galerkin procedures for parabolic and hyperbolic equations by Jim Douglas( Book )

5 editions published in 1974 in English and Undetermined and held by 4 WorldCat member libraries worldwide

A technical method of approximating the Galerkin approximation to solutions of parabolic and hyperbolic equations can be based on a finite sequence of elliptic projections. The resulting function is called a quasi-projection, and it is used to study superconvergence phenomena associated with the Galerkin procedures
A Galerkin Procedure for Approximating the Flux on the Boundary for Elliptic and Parabolic Boundary Value Problems by Jim Douglas( Book )

4 editions published in 1974 in English and held by 4 WorldCat member libraries worldwide

Elliptic and parabolic boundary value problems are first solved approximately on a rectangle and then simple auxiliary calculations are performed on the Galerkin solution to produce higher order correct approximations to the boundary flux than arise from the straightforward differentiation of the Galerkin solution. L sup 2 boundary and L sup infinity estimates are derived for the error. (Author)

1 edition published in 1988 in French and held by 2 WorldCat member libraries worldwide

The works presented in this thesis concern the asymptotic behaviour (as t →∞ ) of dissipative partial differential equations and are mainly dealing with two topics: attractors and inertial manifolds.In the first part, we study the attractors associated with a rather general class of reaction diffusion systems (including systems with an invariant region). We consider both the dissipative case and the partly dissipative case- more complex - where some diffusion coefficients are equal to zero. We prove the existence of universal attractors with finite fractal dimension and we derive estimates of this dimension. Our work relies in particular on generalizations of a class of collective functional inequalities due to Lieb and Thirring which are presented at the end of part one.The second part is devoted to inertial manifolds and their approximation. The existence of inertial manifolds for partly dissipative reaction-diffusion systems is established. We then address several questions related to approximate inertial manifolds. For reaction-diffusion equations, we show that such manifolds exist in high space dimension - as opposed to "exact" inertial manifolds. Then a method for constructing manifolds providing better and better order approximations to the solutions is presented in the case of the Cahn-Hilliard equation. Lastly, we propose numerical schemes well adapted to the long term integration of partial differential equations and stemming from the study of approximate inertial manifolds.The third part deals with problems borrowed from the theory of combustion. We study the qualitative properties of a one-dimensional stationary model for laminar flames. We also investigate the attractors associated with a two-dimensional model in incompressible fluid
