On commutator socle-regular Abelian p-groups [PDF]
, 2014 We define the notion of a commutator socle-regular Abelian p-group. After establishing some crucial properties of commutator socle-regularity, we investigate its relationship with socle-regularity, strong socle-regularity and projection socle ...

In this paper, we investigate properties of varieties of algebras described by a novel concept of equation that we call commutator equation. A commutator equation is a relaxation of the standard term equality obtained substituting the equality relation ...

Relative commutator theory in varieties of Ω-groups [PDF]
, 2007 We introduce a new notion of commutator which depends on a choice of subvariety in any variety of Ω-groups. We prove that this notion encompasses Higgins’s commutator, Fröhlich’s central extensions and the Peiffer commutator of precrossed ...

The self-commutator of a subnormal operator [PDF]
, 1997 This work is directed toward a study of the self-commutator of a subnormal operator. This can lead one in several directions. One place the self-commutator plays an important role is in the C*-algebra generated by a subnormal operator.

On commutativity of rings with constraints involving a nil subset
Proyecciones (Antofagasta), 2018 The main theorem of this paper is that a ring R with unity is commutative if and only if there is a nil subset B of R such thatl. for each x ? R, either x ? Z(R) or there is a polynormial f over Z with x - x2 f (x) ? B;2. for each x, y x ? R, there are non-negative integers n > 1, m, r, s depending on a pair of ring elements x,y with x(xmy ± xrynxs)

On the commutator width of perfect groups
, 2004 This paper proves bounds for the commutator width of a wreath product of two groups. As a corollary, it is shown that the commutator width of finite perfect linear groups of dimension 15 is unbounded.

Mechanical proofs of the Levi commutator problem [PDF]
, 1998 . This note presents purely mechanical proofs of the Levi commutator problem in group theory. The problem was solved first by using the theorem prover EQP, developed by William McCune at the Argonne National Laboratory.
