Nilpotent S-Derivations

open access: yesIndagationes Mathematicae (Proceedings), 1968
AbstractThe structure of fields with nilpotent S-derivations is investigated. General basis theorems are obtained, illustrated with several examples.

Nilpotency property, physicality criteria, constraints and standard BRST algebra: A 4D field-theoretic system

open access: yesNuclear Physics B
Within the framework of Becchi-Rouet-Stora-Tyutin (BRST) formalism, we discuss the off-shell nilpotent (anti-)BRST and the bosonic ghost-scale symmetries of a set of coupled (but equivalent) Lagrangian densities for the four (3 + 1)-dimensional (4D ...

1-Sylvester matrices

open access: yesSpecial Matrices
A nonzero element aa is called 1-Sylvester in a ring RR, if there exist b,c∈Rb,c\in R such that 1=ab+ca1=ab+ca. In this article, we study such elements, mainly in matrix rings over commutative rings.

Some nilpotent and locally nilpotent matrix groups

open access: yesJournal of Pure and Applied Algebra, 1989
The task of the paper under review is a detailed discussion of nilpotent and locally nilpotent matrix groups over ``special'' division rings. The notion of a ``special'' division ring is introduced by the author and denotes a division ring D with the following property: For every finite subset X of D and every finite subset Y of the subring R of D ...
