Resolution of two conjectures by Erdős and Hall concerning separable numbers

Stijn Cambie, Wouter van Doorn

Erdős and Hall defined a pair $(m, n)$ of positive integers to be interlocking, if between any pair of consecutive divisors (both larger than $1$ ) of $n$ (resp. $m$ ) there is a div…

We establish the order of the maximum length of an increasing sequence, bounded by $n$ , in which the largest prime divisor of the elements form a decreasing sequence.

Resolution of Erdős' problems about unimodularity

Stijn Cambie

Letting $δ_{1} (n, m)$ be the density of the set of integers with exactly one divisor in $(n, m)$ , Erdős wondered if $δ_{1} (n, m)$ is unimodular for fixed $n$ . We prove this is false in ge…
