Abstract
We unify the formulation and analysis of Galerkin and Runge–Kutta methods for the time discretization of parabolic equations This together with the concept of reconstruction of the approximate solutions allows us to establish a posteriori superconvergence estimates for the error at the nodes for all methodsGeorgios Akrivis was partially supported by the Institute of Applied and Computational Mathematics FORTH Greece Charalambos Makridakis was partially supported by the RTNnetwork HYKE HPRNCT200200282 the EU Marie Curie Dev Host Site HPMDCT200100121 and the program Pythagoras of EPEAEK II Ricardo H Nochetto was partially supported by NSF grants DMS0505454 and DMS0807811
