The paper is concerned with reliable space-time IgA schemes
for parabolic initial-boundary value problems. We deduce a posteriori
error estimates and investigate their applicability to space-time IgA
approximations. Since the derivation is based on purely functional arguments,
the estimates do not contain mesh dependent constants and are
valid for any approximation from the admissible (energy) class. In particular,
they imply estimates for discrete norms associated with stabilised
space-time IgA approximations. Finally, we illustrate the reliability
and efficiency of presented error estimates for the approximate
solutions recovered with IgA techniques on a model example.

Guaranteed error bounds and local indicators for adaptive solvers using stabilised space-time IgA approximations to parabolic problems
Langer, Ulrich; Matculevich, Svetlana; Repin, Sergey (Elsevier, 2019)The paper is concerned with space–time IgA approximations to parabolic initial–boundary value problems. We deduce guaranteed and fully computable error bounds adapted to special features of such type of approximations and ... -
Guaranteed and computable error bounds for approximations constructed by an iterative decoupling of the Biot problem
Kumar, Kundan; Kyas, Svetlana; Nordbotten, Jan Martin; Repin, Sergey (Elsevier, 2021)The paper is concerned with guaranteed a posteriori error estimates for a class of evolutionary problems related to poroelastic media governed by the quasi-static linear Biot equations. The system is decoupled by employing ... -
Guaranteed lower bounds for cost functionals of time-periodic parabolic optimization problems
Wolfmayr, Monika (Elsevier, 2020)In this paper, a new technique is shown for deriving computable, guaranteed lower bounds of functional type (minorants) for two different cost functionals subject to a parabolic time-periodic boundary value problem. Together ... -
