Abstract
In this paper we give a sense to the distributional multiplicative pro duct (delta(x(0) - \x\)/\x\((n-2)/2))(delta(x(0) + \x\)/\x\((n-2)/2)). For the case n = 4 we obtain a formula which is used for a perturbati ve calculation of Green function in quantum field theories. As an appl ication of our product, we show the calculation of the self-energy of the theory of lambda phi(4).
