摘要
The field-dependent invariant representation ( the dynamical representation) of the Poincare algebra is considered as a dynamical principle in order to get a corresponding dynamical electromagnetic coupling for higher spins (s greater than or equal to 1). If in lower-spin (s = 0, 1/2) cases the dynamical coupling is taken to coincide with the minimal electromagnetic coupling, the higher-spin coupling is inevitably non-minimal, containing a term linear in the field strength tensor F-muv. This non-minimal coupling leads to g = 2.
