In this paper we construct examples of nonextremal locally finite groups for which every finite unsolvable subgroup is not embedded in any proper infinite subgroup. We also give an example of a locally finite simple group, any proper infinite subgroup of which is bigrade solvable....
We present new Hopf algebras with the dual Chevalley property by determining all semisimple Hopf algebras Morita-equivalent to a group algebra over a finite group, for a list of groups supporting a non-trivial finite-dimensional Nichols algebra....

Sets– Sets is defined as the collection of the objects that are determined by some specific property for a set. For example – A set of all the 2×2 matrices, the set of two-dimensional vectors present in the plane and different forms of finite groups. ...

Permutations arise naturally in combinatorics, the theory of finite groups, probability, etc. In particular, in the study of probability, permutations are used to compute the number of possibilities for some event and their associated probabilities.View...

Let M be a left R-module such that M + is a countable, reduced, torsion-free group of finite p-rank for all primes p∈ and assume R=R∩EndM={∈R: MM}. Then there is an exact sequence 0→M→A→F→0 of left R-modules such that A is torsion-free of finite rank with REndA ...
