SophusComputing in nilpotent Lie algebrasA GAP 4 package |
Short description (Abstract)Sophus is a GAP 4 package to compute with nilpotent Lie algebras over finite prime fields. In particular, the package can be used to compute certain central extensions and the automorphism group of such Lie algebras. Sophus also enables its user to test isomorphism between two nilpotent Lie algebras. The author of the package used it to construct all Lie algebras of dimension at most 9 over GF(2) and those of dimension at most 7 over GF(3) and GF(5); follow this link for details. |
DownloadThe package can be accessed in a compressed format. The files README and PackageInfo.g can be downloaded separately.Current version 1.23: [README] [sophus1r23.tar.gz] [PackageInfo.g] Download the sophus1r23.tar.gz file above and place it in your gap/pkg directory. Then type tar xvzf sophus1r23.tar.gz Next time you run GAP you have to type gap> LoadPackage( "sophus" ); --------------------------------------------------------------- Loading Sophus 1.23 (Computing with nilpotent Lie algebras) by Csaba Schneider (http://www.sztaki.hu/~schneider). --------------------------------------------------------------- true See the GAP manual for further details. |
