Collocation methods for parabolic equations in a single space variable, based on C¹ piecewise-polynomial spaces by Jim Douglas ( Book )
17 editions published between 1974 and 2008 in 3 languages and held by 97 WorldCat member libraries worldwide
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 5 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 )
5 editions published in 1974 in English and Undetermined 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)
Projection Methods for Dirichlet's Problem in Approximating Polygonal Domains with Boundary Value Corrections by J. H Bramble ( Book )
3 editions published in 1972 in English and held by 3 WorldCat member libraries worldwide
Accurate approximate methods for solving Dirichlet's problem in a plane domain which consist in applying projection methods on an approximating polygonal domain are described and analyzed. (Author)

Mixed Finite Element Methods for Time Dependent Problems: Application to Control ( )
1 edition published in 1989 in English and held by 1 WorldCat member library worldwide
The main goal of this paper is to discuss mixed variational formulations for time dependent problems such as initial and boundary value problems for the heat and wave equations in a bounded domain Omega of R-superscript-N(N>or= 1). Then we shall use these formulations to derive mixed finite element approximations of the heat and wave equations. Finally an application to an exact boundary controllability problem for the wave equation will be presented together with some numerical results. The techniques and application briefly considered here will be discussed with more details in a forthcoming paper
Some Superconvergence Results for an (H sup 1)-Galerkin Procedure for the Heat Equation ( Book )
1 edition published in 1973 in English and held by 1 WorldCat member library worldwide
SDouglas, Jim, Jr.;Dupont, Todd ;Wheeler, Mary Fanett ;MRC-TSR-1382DA-31-124-ARO(D)-462Sponsored in part by National Science Foundation.*Heat transfer, *Partial differential equations, Calculus of variations, Convergence, Approximation, Theorems*Galerkin method, Parabolic differential equations, Heat equationThomee and Wahlbin have introduced a Galerkin method for the heat equation in a single space variable based on the (H sup 1)-inner product and have obtained (H sup 2) and (H sup 1) estimates for the error. An (L sup 2) estimate is given here. The main object is to show knot superconvergence phenomena when the subspace is a piecewise-polynomial space. For (C sup 2)-piecewise-polynomials of degree r, the error in the knot values is O(h sup(2r-2)); for the (C sup 1) case, both knot values and knot first x-derivatives are approximated to within O(h sup(2r-2)).
