The generating functional of the lsing model is studied. Equations of motion for the generating functional and the hierarchy of Green's functions are derived. These equations resemble a scalar field theory with nonlinear derivative coupling. Such a formulation bridges the gap between the Ising model

Radiation of a massive classical scalar field from a point source is studied in the mass zero limit and compared with the radiation emitted in a mass zero theory. The total radiated energy momentum is the same in both theories, but the rate cannot be got in the massive theory. The massive theory adm
