Universal Taylor Series On Convex Subsets Of Mathbb{C}^(N)

We prove the existence of holomorphic functions $f$ defined on any open convex subset ${\rm \Omega}\subset {{\mathbb C}}^n$, whose partial sums of the Taylor developments approximate uniformly any complex polynomial on any convex compact set disjoint from $\bar{{\rm \Omega}}$ and on denumerably many convex compact sets in ${{\mathbb C}}^n\backslash {\rm \Omega}$ which may meet the boundary $\partial {\rm \Omega}$. If the universal approximation is only required on convex compact sets disjoint from $\bar{{\rm \Omega}}$, then $f$ may be chosen to be smooth on $\partial {\rm \Omega}$, that is $f\in A^{\infty}({\rm \Omega})$. Those are generic universalities.
