the author studies the $bf r$$g$-module $a$ such that $bf r$ is an associative ring, a group $g$ has infinite section $p$-rank (or infinite 0-rank), $c_{g}(a)=1$, and for every proper subgroup $h$ of infinite section $p$-rank (or infinite 0-rank respectively) the quotient module $a/c_{a}(h)$ is a finite $bf r$-module. it is proved that if the group $g$ under consideration is local...
let $g$ be a finite group. in [ghasemabadi et al., characterizations of the simple group ${}^2d_n(3)$ by prime graph and spectrum, monatsh math., 2011] it is proved that if $n$ is odd, then ${}^2d _n(3)$ is recognizable by prime graph and also by element orders. in this paper we prove that if $n$ is even, then $d={}^2d_{n}(3)$ is quasirecognizable by prime graph, i.e...
we consider the class $mathfrak m$ of $bf r$--modules where $bf r$ is an associative ring. let $a$ be a module over a group ring $bf r$$g$, $g$ be a group and let $mathfrak l(g)$ be the set of all proper subgroups of $g$. we suppose that if $h in mathfrak l(g)$ then $a/c_{a}(h)$ belongs to $mathfrak m$. we investigate an $bf r$$g$--module $a$ such that $g not = g'$, $c_{g}(a) = 1$. we stud...
let $g$ be a finite group. we construct the prime graph of $ g $,which is denoted by $ gamma(g) $ as follows: the vertex set of thisgraph is the prime divisors of $ |g| $ and two distinct vertices $ p$ and $ q $ are joined by an edge if and only if $ g $ contains anelement of order $ pq $.in this paper, we determine finite groups $ g $ with $ gamma(g) =gamma(l_3(q)) $, $2 leq q < 100 $ and prov...

let $g $ be a finite group and let $gamma(g)$ be the prime graph of g. assume $2 < q = p^{alpha} < 100$. we determine finite groups g such that $gamma(g) = gamma(u_3(q))$ and prove that if $q neq 3, 5, 9, 17$, then $u_3(q)$ is quasirecognizable by prime graph, i.e. if $g$ is a finite group with the same prime graph as the finite simple group $u_3(q)$, then $g$ has a un...
let l := u3(11). in this article, we classify groups with the same order and degree pattern as an almost simple group related to l. in fact, we prove that l, l:2 and l:3 are od-characterizable, and l:s3 is 5-fold od-characterizable.

in this paper we will prove that the simple group g2(q) where 2 < q = 1(mod3)is recognizable by the set of its order components, also other word we prove that if g is a nite group with oc(g) = oc(g2(q)), then g is isomorphic to g2(q).
