El producto distribucional entre la parte finita de (formula) en (formula) y (formula) de la derivada k- ésima de la delta de Dirac en un hipercono

Let P Px1 , . . . . ,xn be a quadratic form in n variables defined by (1) and let P be the distribution defined by (3) where is a complex number. Using the Laurent series of P and considering the signature p,q of Px we given a sense to distributional products P .P,P n 2 h .LP and P n 2 s . n 2 P, where P ,P n 2 t we means finite part of P at r,r 1,2, . . . and n 2 t, t 1,2, . . , t 0,1, . . ,P is defined by (13) and L si a linear homogeneous differential operator iterated s-times defined by (18).
