Abstract
Asymptotic expansions in powers of δ as δ → +∞ of the series
where β ∈ ℤ, α, a, b > 0, and r ∈ ℂ, while Q is an algebraic polynomial satisfying the condition Q(0) = 0, are obtained. In special cases, these series arise from the approximation of periodic differentiable functions by the Riesz and Cesàro means.
