+ | ** 10/16/09 DWS ** Working on the Floquet exponents/multipliers of the new periodic orbits. I wanted them to be in the correct size boxes before I calculated them.

+ | ** 10/17/09 DWS ** I think the 5th imaginary value above should be zero as the arg(Λ) was π. | ||

+ | |||

+ | ** 10/20/09 PC ** There is no point doing these tables in dokuwiki format. You need them in your thesis, and John and I have to agree on how to present periodic orbits in our periodic orbits paper, so I have toiled away for past two days on a proposal how to tabulate them. DWS, JFG, ES, and RLD, please check out ChaosBook.org section [[http://chaosbook.org/chapters/appendStability.pdf|B.3 Eigenspectra: what to make out of them?]]. | ||

+ | |||

+ | ** 10/21/09 DWS ** Okay, so after a few passes I think I understand everything you propose we calculate for the periodic orbits. I also got my svn working again and I will put the tables in there for my thesis. I am not 100% sure, but I believe that the eigenvectors produced by arnoldi iteration are orthogonal because I believe that arnoldi iteration, by definition, uses the stabilized Gram-Schmidt process. I also checked a number of eigenvectors that I produced using the arnoldi utility and by using the L2IP function, I found that the inner product between two different eigenvectors was always very close to 0, usually within 10^-5. I would like confirmation of this from John G., though. | ||
