Adaptive Computational Methods for Parabolic Problems
Kapitel i bok, 2017
We present a unified methodology for the computational solution of parabolic systems of differential equations with adaptive selection of discretization in space and time, based on a posteriori error estimates involving residuals of computed solutions and stability factors/weights, obtained by solving an associated linearized dual problem. We define parabolicity as boundedness in time (up to logarithmic factors) of a certain strong stability factor measuring the L[[inf]]1[[/inf]](L[[inf]]2[[/inf]])-norm in time-space of the time derivative of the dual solution with L[[inf]]2[[/inf]]-normalized initial data.
