A new generalization of the Genocchi numbers and its consequence on the Bernoulli polynomials

Abstract: This paper presents a new generalization of the Genocchi numbers and the Genocchi theorem. As consequences, we obtain some important families of integer-valued polynomials those are closely related to the Bernoulli polynomials. Denoting by ${(B_n)}{n \in \mathbb{N}}$ the sequence of the Bernoulli numbers and by ${(B_n(X))}{n \in \mathbb{N}}$ the sequence of the Bernoulli polynomials, we especially obtain that for any natural number $n$, the reciprocal polynomial of the polynomial $\big(B_n(X) - B_n\big)$ is integer-valued.
