SIAM Journal on Numerical Analysis, Vol. 48, No. 4 (2010), pp. 1281-1312 (32 pages) We develop a mixed finite element method for elliptic problems on hexahedral grids that reduces to cell-centered ...
Uniform $\mathscr{O}(h^2)$ convergence is proved for the El-Mistikawy-Werle discretization of the problem $-\varepsilon u'' + au' + bu = f$ on (0, 1), $u(0) = A, u(1 ...
