Let \( {\mathfrak{M}} \) be a set of finite groups. Given a group \( G \), denote the set of all subgroups of \( G \) isomorphic to the elements of \( {\mathfrak{M}} \) by \( {\mathfrak{M}}(G) \). A group \( G \) is called saturated by groups in \( {\mathfrak{M}} \) or by \( {\mathfrak{M}} \) for brevity, if each finite subgroup of \( G \) lies in some element of \( {\mathfrak{M}}(G) \). We prove that every locally finite group \( G \) saturated by \( {\mathfrak{M}}=\{GL_{m}(p^{n})\} \), with \( m>1 \) fixed, is isomorphic to \( GL_{m}(F) \) for a suitable locally finite field \( F \).

具有有限子群规定结构的局部有限群

令 \({\ mathfrak {M}} \) 为一组有限组。给定一组 \(G \) ,表示该组的所有子组的 \(G \) 同构的元素 \({\ mathfrak {M}} \)由 \({\ mathfrak {M}}(G) \)。A组 \(G \) 通过基团中称为饱和 \({\ mathfrak {M}} \) 或通过 \({\ mathfrak {M}} \)为简化起见,如果每个有限子群 \(G \) 位于\({\ mathfrak {M}}(G)\)的某个元素中 。我们证明每个局部有限群 \(G \)\({\ mathfrak {M}} = \ {GL_ {m}(p ^ {n})\} \)饱和 ,其中 \(m> 1 \) 固定, 对于合适的局部有限域 \(F \)\(GL_ {m}(F)\)的同构 。
