An easily computable error estimator in space and time for the wave equation
Olga Gorynina, Alexei Lozinski, Marco Picasso
We propose a cheaper version of \textit{a posteriori} error estimator from arXiv:1707.00057 for the linear second-order wave equation discretized by the Newmark scheme in time and…

Time and space adaptivity of the wave equation discretized in time by a second order scheme
Olga Gorynina, Alexei Lozinski, Marco Picasso
The aim of this paper is to obtain a posteriori error bounds of optimal order in time and space for the linear second-order wave equation discretized by the Newmark scheme in time…
