Abstract:
The arithmetic partial derivative (with respect to a prime p) is a
function from the set of integers that sends p to 1 and satisfies
the Leibniz rule. In this paper, we prove that the p-adic valuation
of the sequence of higher order partial derivatives is eventually
periodic. We also prove a criterion to determine when an integer has
integral anti-partial derivatives. As an application, we show that
there are infinitely many integers with exactly n integral anti-partial
derivatives for every nonnegative integer n.
