On characterization of groups by isomorphism type of Gruenberg-Kegel graph

Mingzhu Chen, Natalia V. Maslova, Marianna R. Zinov'eva

The Gruenberg-Kegel graph (or the prime graph) $I^ (G)$ of a finite group $G$ is the graph whose vertex set is the set of prime divisors of $∣ G ∣$ and in which two distinct vertices…

On combinatorial properties of Gruenberg--Kegel graphs of finite groups

Mingzhu Chen, Ilya B. Gorshkov, Natalia V. Maslova +1

If $G$ is a finite group, then the spectrum $I ¨ (G)$ is the set of all element orders of $G$ . The prime spectrum $I ¨ (G)$ is the set of all primes belonging to $I ¨ (G)$ . A simple grap…
