Finite group with given c-permutable subgroups Ahmad Alsheik Ahmad Following [1] we say that subgroups H and T of a group G are c-permutable in G if there exists an element x ∈ G such that HTˣ = TˣH. We prove that a finite soluble group G is supersoluble if and only if every maximal subgroup of every Sylow subgroup of G is c-permutable with all Hall subgroups of G.

Some applications of Hasse principle for pseudoglobal fields Andriychuk, V. Some corollaries of the Hasse principle for Brauer group of a pseudoglobal field are obtained. In particular we prove Hasse-Minkowski theorem on quadratic forms over pseudoglobal field and the Hasse principle for quadratic forms of rank 2 or 3 over the field of fractions of an excellent two-dimensional henselian local domain with pseudofinite residue field. It is considered also the Galois group of maximal p-extensions of a pseudoglobal field.

A note to my paper “Multi-algebras from the viewpoint of algebraic logic” Cırulis, J. The definition of a resolvent, introduced in the paper mentioned in the title, is simplified, and some misprints in that paper are corrected.

On the Tits alternative for some generalized triangle groups Beniash-Kryvets, V.; Barkovich, O. In the paper Rosenberger’s conjecture is proved for groups T(2, l, 2, R) with l = 6, 12, 30, 60 and some special groups T(3, 4, 2, R). Remove selected
