Computational Techniques for Lyapunov Exponents and Vectors
23 Mar 2015 | Presentations | Contributor(s): Erik Van Vleck
In this talk we present computational techniques for Lyapunov exponents and vectors based upon continuous matrix factorizations (QR and SVD). We outline the techniques, their well-posedness, error...
