Abstract

The sequence A(n)n0A(n)_{n \geq 0} of Ap\'ery numbers can be interpolated to C\mathbb{C} by an entire function. We give a formula for the Taylor coefficients of this function, centered at the origin, as a Z\mathbb{Z}-linear combination of multiple zeta values. We then show that for integers nn whose base-pp digits belong to a certain set, A(n)A(n) satisfies a Lucas congruence modulo p2p^2.
