Pointwise a posteriori error analysis for an adaptive penalty finite element method for the obstacle problem.
Origins, analysis, numerical analysis, and numerical approximation of a forward-backward parabolic problem
Origins, analysis, numerical analysis, and numerical approximation of a forward-backward parabolic problem
We consider the analysis and numerical solution of a forward-backward boundary value problem. We provide some motivation, prove existence and uniqueness in a function class especially geared to the problem at hand, provide various energy estimates, prove error estimates for the Galerkin method, and show the results of some numerical computations.
