In this paper, three a posteriori error estimators of the error in the semidiscrete ยฎnite element solution (discrete in space and continuous in time) of parabolic partial dierential equations are analyzed. This approach is based on a posteriori error estimators for the elliptic PDEs. It is proven th
Using the abstract framework of [R. Verfรผrth, Math. Comput. 62, 445-475 (1996)], we analyze a residual a posteriori error estimator for space-time finite element discretizations of parabolic PDEs. The estimator gives global upper and local lower bounds on the error of the numerical solution. The fin
