On an Alternating Double Sum of a Triple Product of Aerated Binomial Coefficients
Published 13 Jun 2023 in math.GM | (2306.08022v1)
Abstract: The double sum sum_(j=0)m sum_(i=0)j (-1)j-i C(m,j) C(j,i) C(j+k+qi,j+k) with free nonnegative integer parameters k and q is rewritten as hypergeometric series. Efficient formulas to generate the C-finite ordinary generating functions are presented.
