Convolution identities for Tribonacci numbers via the diagonal of a bivariate generating function (1910.08323v1)
Published 18 Oct 2019 in math.NT and math.CO
Abstract: Convolutions for Tribonacci numbers involving binomial coefficients are treated with ordinary generating functions and the diagonalization method of Hautus and Klarner. In this way, the relevant generating function can be established, which is rational. The coefficients can also be expressed. It is sketched how to extend this to Tetranacci numbers and similar quantities.
