FundAlphabet

FundAlphabet

is an option for the routine DefineGaugeGroup that specifies a printing alphabet for the indices of the fundamental representation.

Details and Options

  • The canonic indices of the fundamental representation that are obtained by invoking functions like RelabelIndices print with the labels specified in FundAlphabet when using NiceForm.

Examples

Basic Examples  (1)

Define a SU(3) gauge group with fundamental alphabet "a", "b", "c","d":

Define a field transforming under under adjoint of this gauge group:

NiceForm printing of the fields with given labels:

NiceForm printing of the fields with canonic labels:

If more canonic labels are present than symbols specified in FundAlphabet, the labels are repeated with additional integer subscripts to distinguish the indices:
