Nonlinear
Generalizations of the Klein
Gordon Equation
The field
equations for spin-zero meson fields used in the derivation of
SWEPs are nonlinear generalization of the well known Klein-Gordon equation. They are
of the form1:
J is the meson filed self
interaction current. lI (i=1…n)
are self interaction coupling constants.
