Abstract

The problem of defining products of distributions is a difficult and not completely understood problem, studied from several points of views since Schwartz established the theory of distributions around 1950. Many fields, such as wave propagation or quantum mechanics, require such multiplications. The product of an infinitely differentiable function (x) and distribution 4(x) inRn is well defined by since  Using an induction, we derive an interesting formula for  and hence we are able to write out an explicit expression of the product  In particular, we imply the product  with a few applications in further simplifying existing distributional products. Furthermore, we obtain an asymptotic expression for which isequivalent to the well-known Pizzetti’s formula. Several asymptotic products including  as wellasthemore generalized  are calculated and presented as infinitely series.
