چکیده
Let G be a finite group, and let Δ(G) the prime graph built on its set of conjugacy class sizes: this is (simple undirected) whose vertices are numbers dividing some size G, two distinct p, q adjacent if only pq divides G. In paper, we characterize structure those groups block square.

Groups whose set of vanishing elements is exactly a conjugacy class
Let $G$ be a finite group. We say that an element $g$ in $G$ is a vanishing element if there exists some irreducible character $chi$ of $G$ such that $chi(g)=0$. In this paper, we classify groups whose set of vanishing elements is exactly a conjugacy class.
متن کاملquasirecognition by prime graph of finite simple groups ${}^2d_n(3)$
let $g$ be a finite group. in [ghasemabadi et al., characterizations of the simple group ${}^2d_n(3)$ by prime graph and spectrum, monatsh math., 2011] it is proved that if $n$ is odd, then ${}^2d _n(3)$ is recognizable by prime graph and also by element orders. in this paper we prove that if $n$ is even, then $d={}^2d_{n}(3)$ is quasirecognizable by prime graph, i.e...
متن کاملSome Results on Finite Groups Whose Order Contains a Prime to the First Power
In a previous investigation [1], the author has studied finite groups © of an order g = pgo where p is a prime and go an integer not divisible by p. This work has been continued by H. F. Tuan [51 Let t denote the number of conjugate classes of ® which consist of element of order p. Tuan dealt with the groups ® for which t^2 and which have a faithful representation of degree less than p 1. We sh...
متن کاملCharacterization and axiomatization of all semigroups whose square is group
In this paper we give a characterization for all semigroups whose square is a group. Moreover, we axiomatize such semigroups and study some relations between the class of these semigroups and Grouplikes,introduced by the author. Also, we observe that this paper characterizes and axiomatizes a class of Homogroups (semigroups containing an ideal subgroup). Finally, several equivalent conditions ...
متن کاملThe structure of finite groups with three class sizes
Let G be a finite group and suppose that the set of conjugacy class sizes of G is f1;m;mng, where m; n > 1 are coprime. We prove that m 1⁄4 p for some prime p dividing n 1. We also show that G has an abelian normal p-complement and that if P is a Sylow p-subgroup of G, then jP 0j 1⁄4 p and jP=ZðGÞpj 1⁄4 p. We obtain other properties and determine completely the structure of G.
