Web7 de fev. de 2015 · Any collection of elements in a group, finite or infinite, always generates some subgroup. This is in particular always true for a single element of the group. Sometimes, however, the generated subgroup may be the entire group. (But any group is a subgroup of itself, so this is not a contradiction). WebIn mathematics, a von Neumann algebra or W*-algebra is a *-algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator.It is a special type of C*-algebra.. Von Neumann algebras were originally introduced by John von Neumann, motivated by his study of single operators, group …

By hypothesis H is weakly s-permutable in G and so by Lemma 2.10 (5), G has a normal subgroup T such that G : T is prime and HT = G. It follows that NT = G, T ∩ N is a maximal subgroup of N and T ∩ N is normal in G, a contradiction.
