Events: 3rd Workshop on Model Reduction for Complex Dynamical Systems

January 11th, 2017
P. Benner, H. Faßbender, M. Hinze, R. Zimmermann, T. Stykel organize the MODRED 2017, January 11-13, 2017 at the Department of Mathematics and Computer Science (IMADA), University of Southern Denmark, Odense.

Preprint: Combined Error Estimates for Local Fluctuations of SPDEs

November 14th, 2016
In this work, Christian Kuehn and Patrick Kürschner study the numerical approximation of local fluctuations of certain classes SPDEs. Combined ERror EStimates (CERES) are developed for the four main errors: the spatial discretization error, the local linearization error, the local relaxation error to steady state, and the approximation error w.r.t. the covariance matrix computed by an iterative low-rank algorithm for Lyapunov equations.
