Graphs with girth 9 and without longer odd holes are 3-colorable

Yan Wang, Rong Wu

For a number $l \geq 2$ , let $G_{l}$ denote the family of graphs which have girth $2 l + 1$ and have no odd hole with length greater than $2 l + 1$ . Wu, Xu and Xu conjectured that e…

Borodin-Kostochka conjecture for a family of $P_{6}$ -free graphs

Di Wu, Rong Wu

Borodin and Kostochka conjectured that every graph $G$ with $Δ \geq 9$ satisfies $χ \leq$ max ${ω, Δ - 1}$ . Gupta and Pradhan proved the Borodin-Kostochka conjecture for ( $P_{5}$ , $C_{4}$ )-…

Mobius disjointness conjecture on the product of a circle and the Heisenberg nilmanifold

Jing Ma, Ronghui Wu

Let $T$ be the unit circle and $Γ ∖ G$ the 3-dimensional Heisenberg nilmanifold. We prove that the Möbius function is linearly disjoint from a class of distal skew…

On a sum involving general arithmetic functions and the integral part function

Jing Ma, Ronghui Wu

Let $f$ be an arithmetic function satisfying some simple conditions. The aim of this paper is to establish an asymptotical formula for the quantity \[ S_f(x):=\sum_{n\leq x}\frac{f…

The 4-Component Connectivity of Alternating Group Networks

Jou-Ming Chang, Kung-Jui Pai, Ro-Yu Wu +1

The $ℓ$ -component connectivity (or $ℓ$ -connectivity for short) of a graph $G$ , denoted by $κ_{ℓ} (G)$ , is the minimum number of vertices whose removal from $G$ results in a d…
