Truncating expansions in bi-orthogonal bases: What is preserved?

In this work, we test the survival of topological information of an attractor under the truncations of a bi-orthogonal decomposition. We generate synthetic patterns which evolve dynamically in a desired way, and investigate the number of modes which should be kept in a truncation in order to be able...

description In this work, we test the survival of topological information of an attractor under the truncations of a bi-orthogonal decomposition. We generate synthetic patterns which evolve dynamically in a desired way, and investigate the number of modes which should be kept in a truncation in order to be able to recover the information which we provided to the system. We show that a premature truncation of this kind of decomposition, based on existing energy criteria, leads to orbits that do not preserve the topological properties of the original signal. © 1997 Elsevier Science B.V.
