# mathematical explanation for UV divergences and $\delta ^{(n)}(0)$

is there any mathematical explanation for the UV divergences ??

i have read that in the framework of Epstein-Glser theory :D these UV divergences appear from the product of distributions

anyone does the numbers (divergences) of the form $\delta ^{(n)}(0)$ have a meaning within the renormalization framework ?? since $\delta ^{(n)}(0)=i^{n} \int_{-\infty}^{\infty}dx x^{n}$
