A Galerkin procedure for approximating the flux on the boundary for elliptic and parabolic boundary value problems by Jim Douglas( Book )

6 editions published in 1974 in English and held by 5 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)
A Quasi-Projection Approximation Method Applied to Galerkin Procedures for Parabolic and Hyperbolic Equations by Jim Douglas( Book )

6 editions published in 1974 in English 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

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)).
