Abstract

In this article, we give a positive answer to a question posed in 1960 by D.S. Mitrinovi\'{c} and R.S. Mitrinovi\'{c} (see: D.S. Mitrinovi\'{c} et R.S. Mitrinovi\'{c}, Tableaux qui fournissent des polyn\^{o}mes de Stirling, Publications de la Facult\'{e} d'Electronique, s\'{e}rie: Math\'{e}matiques et physique, 34, (1960).1-23.) concerned the Stirling numbers of the first kind s(n,k).s(n,k). We prove that for all k2k\geq 2 there exist an integer mkm_{k} and a primitive polynomial Pk(x)P_{k}(x) in Z[x]\mathbb{Z}[x] such that for all nkn\geq k, s(n,nk)=1mk(nk+1)(n(n1))mod(k,2)Pk(n)s(n,n-k)=\frac{1}{m_{k}}\binom{n}{k+1}\left(n(n-1)\right) ^{\mathop{\rm mod}\nolimits (k,2)}P_{k}(n). Moreover for all k1k\geq1, P2k(0)=P2k+1(0)P_{2k}(0)=P_{2k+1}(0).
