GAP4 script files for Lie algebras
Download page
The following simple GAP4 script files complement the paper "Angular momentum non conserving symmetries in bosonic models" by L.Fortunato and W.A. de Graaf (2011) u2.g --> implementation of u(2) algebra in terms of scalar bosons
u2xu2.g --> implementation of u(2)xu(2) algebra in terms of two sets of scalar bosons
u3.g --> implementation of u(3) algebra in terms of a vector boson
u4vibron.g --> implementation of the u(4) algebra of the Vibron model.
rootsys.g --> A function written by Willem de Graaf that is called by the u(3) and u(4) files.
cyc2rad.g --> A function written by me that is used to transform cyclotomic numbers used by GAP4 in readable square roots and fractions. I suggest modifying your gap.rc file in the bin directory by adding the line: Read("../cyc2rad.g"); with appropriate path.
symplectic2pZ.g --> Available soon
symplectic2pX.g --> Available soon
