DefineCGGroup

DefineCGGroup[groupName,alg]

defines a new group with which to create and manipulate CG objects with reference name groupName. alg sets the Lie algebra of the group.

Details and Options

  • DefineCGGroup does not give a return value, but modifies the internal state of Matchete, initializing a new Lie group.
  • The algebra argument must be a valid Alg[class, n] object.
  • When using groups to define internal symmetries of Lagrangians (theories), the user should more likely use the more specialized DefineGaugeGroup or DefineGlobalGroup instead.
