Abstract
Mikusiński in [1] has proved that the product of the distributions δ (x) and pf. \(\frac{1} {{\text{x}}}\) on the one-dimensional Euclidean space ℝ exists in the sense of generalized operations and equals \(- \frac{1} {{\text{2}}}\delta \prime \left( {\text{x}} \right)\). This result can be easily extended to the case of an n-dimensional Euclidean space ℝn, i.e. for any \(\ell = \left( {\ell _1,\ell _2, \ldots,\ell _{\text{n}} } \right) \in R^{\text{n}},\left( {\ell \ne 0} \right)\),
where \(\left( {\ell,{\text{x}}} \right) = \sum\limits_{{\text{k}} = 1}^{\text{n}} {\ell _{\text{k}} {\text{x}}_{\text{k}}}\).
In this paper we shall try to extend the above results to the case of an infinite dimensional space i.e. an abstract Wiener space.
