Relèvement des coefficients binômiaux dans les vecteurs de Witt

Abstract. The purpose of this work is to describe certain elements of the ring W(Z) of the (big) Witt vectors with coefficients in Z whose properties are very similar with the properties of the binomial coefficients. We prove both a binomial formula and a Pascal formula. By means of those elements we can construct a W(Z)-algebra of divided fractional powers.
