The purpose of this paper is to obtain a relation between the distribution δ ( 2 j ) ( r ) and the operator △ j δ and to give a sense to the convolution distributional product δ ( 2 j ) ( r ) ∗ δ ( 2 s ) ( r ) and the multiplicative distributional products r − k ⋅ ∇ ( △ j δ ) and ( r − c ) − k ⋅ ∇ ( △ j δ ) .
