On arithmetic progressions of positive integers avoiding $p + F_{m}$ and $q + L_{n}$

Rui-Jing Wang

In this paper, it is proved that there is an arithmetic progression of positive integers such that each of which is expressible neither as $p + F_{m}$ nor as $q + L_{n}$ , where $p, q$ are…

On a problem of Pongsriiam on the sum of divisors, II

Rui-Jing Wang

For any positive integer $n$ , let $I ¨ (n)$ be the sum of all positive divisors of $n .$ In this paper, it is proved that the set of positive integers $n$ for which $ Ï(30n+1)\geq…

Rui-Jing Wang

For any positive integer $n$ , let $I ¨ (n)$ be the sum of all positive divisors of $n .$ In this paper, it is proved that for every integer $1 \leq k \leq 29, (k, 30) = 1,$ we have $$\s…
