Model reduction by separation of variables: a comparison between Hierarchical Model reduction and Proper Generalized Decomposition

Numerical Analysis 2023-08-08 v1

Abstract

Hierarchical Model reduction and Proper Generalized Decomposition both exploit separation of variables to perform a model reduction. After setting the basics, we exemplify these techniques on some standard elliptic problems to highlight pros and cons of the two procedures, both from a methodological and a numerical viewpoint.
