AbstractThe local adaptive Galerkin bases for large dynamical systems, whose long time behaviour is confined to a finite dimensional manifold, are bases chosen by a local version of a singular value decomposition analysis. We show that these bases are picked out by choosing directions of maximum bending of the manifold. We discover a useful way to compute the dimension and local shape of the manifold. The application of the results is evaluated by examining numerically several interesting examples.
