On the mixed metric dimension of -connected graphs
Shi Chen, Xuanlong Ma
The paper proves that any 2‑connected graph that is not a cycle has mixed metric dimension at most twice its cyclomatic number, and uses this bound to settle a conjecture of Sedlar…
On finite groups whose coprime graph is a divisor graph
Xuanlong Ma, Liangliang Zhai, Nan Gao +1
In this paper, we first characterize which generalized lexicographic products are divisor graphs. As applications, we show that power graphs, reduced power graphs and order graphs…
The diameter and dominating sets of the difference graph of a nilpotent group
Xuanlong Ma, Samir ZahiroviÄ, Katarina ŽigeroviÄ
Given a finite group , the difference graph of , denoted by , is the difference of the enhanced power graph of and the power graph of , with all isolat…
Forbidden subgraphs on conjugacy class graphs of groups
Papi Ray, Sonakshee Arora, Xuanlong Ma
Let be a finite group. The commuting (resp. nilpotent) conjugacy class graph (resp. ) of is a simple graph whose vertex set consists of all non-c…
(Total) Perfect codes in (extended) subgroup sum graphs
Xuanlong Ma, Yuefeng Yang, Liangliang Zhai
Given a finite group with identity and a normal subgroup of , the subgroup sum graph (resp. extended subgroup sum graph ) of with respect…
