tFundf

tFundf[group]

is the standard name for a Clebsch-Gordan coefficient =fABC, where f is the structure constant (fStruct) and t the generator of the fundamental representation (gen[group@ fund]).

Details and Options

  • The CG tFundf[group] is initialized with the declaration of the (gauge or global) group named group.

Examples

Basic Examples  (1)

If we initialize a new SU(4) group Gr, tFundf[Gr] will refer to the three-index symmetric CG and can be used as shorthand to input the CG:

Observe that the contraction of the structure constant with the generator of the fundamental representation is correctly identified with the tFundf CG:
