Matrix oriented reduction of space-time Petrov-Galerkin variational problems

Julian Henning, Davide Palitta, Valeria Simoncini +1

Variational formulations of time-dependent PDEs in space and time yield $(d + 1)$ -dimensional problems to be solved numerically. This increases the number of unknowns as well as the…

Decay of the Kolmogorov $N$ -width for wave problems

Constantin Greif, Karsten Urban

The Kolmogorov $N$ -width $d_{N} (M)$ describes the rate of the worst-case error (w.r.t.\ a subset $M \subset H$ of a normed space $H$ ) arising from a projection ont…
