Let p be an odd prime, and let k be a nonzero nature number. Suppose that nonabelian group G is a central extension as follows $$1 \to G\prime \to G \to {{\mathbb{Z}}_{{p^k}}} \times \cdots \times {{\mathbb{Z}}_{{p^k}}},$$ where G′ ≅ ℤpk, and

The aim of this paper is to determine the structure and to establish the isomorphic invariant of the finitely generated nilpotent group G of infinite cyclic commutator subgroup. Using the structure and invariant of the group which is the central exte

In this paper we study the saturated fusion systems over a direct product of the extraspecial group of order p3 of exponent p and a finite abelian p-group. The result provides some new exotic fusion systems, whose unique components are isomorphic to

Let G be an extension of ℚ by a direct sum of r copies of ℚ. (1) If G is abelian, then G is a direct sum of r + 1 copies of ℚ and AutG ≅ GL(r + 1, Q); (2) If G is non-abelian, then G is a direct product of an extraspecial ℚ-group E and m co

The automorphism group of a class of nilpotent groups with infinite cyclic derived subgroups is determined. Let G be the direct product of a generalized extraspecial ℤ-group E and a free abelian group A with rank m, where $$E = \left\{ {\left( {\be

Let G be a polycyclic group and α a regular automorphism of order four of G. If the map φ: G → G defined by gφ = [g,α] is surjective, then the second derived group of G is contained in the centre of G. Abandoning the condition on surjectivity,

In this paper, an interaction integral is applied to evaluate the crack-tip field intensity factors for piezoelectric cracks by using BEM. Based on this, the fracture parameters for different crack configurations and loading conditions are analyzed i

Let G and N be arbitrary groups. In this paper, we construct an associated group extension ℰχ of N/Z(N) by G for any group homomorphism χ: G → OutN, and prove that χ can be lifted to a group action, that is, a group homomorphism from G to AutN

We consider sufficient conditions for metacyclic groups to split. Specifically, we show that a finite metacyclic group G of odd order is split on its cyclic normal subgroup K if K is such that G/K is cyclic and |K| = exp G. Розглянуто до
