Strange and pseudo-differentiable functions with applications to prime partitions

Number Theory 2025-05-01 v2

Abstract

Let pPr(n)\mathfrak{p}_{\mathbb{P}_r}(n) denote the number of partitions of nn into rr-full primes. We use the Hardy-Littlewood circle method to find the asymptotic of pPr(n)\mathfrak{p}_{\mathbb{P}_r}(n) as nn \to \infty. This extends previous results in the literature of partitions into primes. We also show an analogue result involving convolutions of von Mangoldt functions and the zeros of the Riemann zeta-function. To handle the resulting non-principal major arcs we introduce the definition of strange functions and pseudo-differentiability.
