On properties of commutative Alexander quandles
Journal of Knot Theory and Its Ramifications, 2014An Alexander quandle Mt is an abelian group M with a quandle operation a * b = ta + (1 - t)b where t is a group automorphism of the abelian group M. In this paper, we will study the commutativity of an Alexander quandle and introduce the relationship between Alexander quandles Mt and M1-t determined by group automorphisms t and 1 - t, respectively.

Some Properties of Commutators and the Equations of Motion
Physica Scripta, 1977In this paper we calculate the commutators of operator functions for non-commuting operators on a Heisenberg ring. The commutator of two operators can be expressed with the help of the fundamental operators and their differentials. Using the theorem of the derivative of a function of operators with respect to any parameter, we can find tne equation of ...

Some properties of commuting and anti-commuting m-involutions
Acta Mathematica Scientia, 2012Abstract We define an m-involution to be a matrix K ∈ ℂ n × n for which Km = I. In this article, we investigate the class Sm (A) of m-involutions that commute with a diagonalizable matrix A ∈ ℂ n × n .

Diophantine properties of finite commutative rings
Archive for Mathematical Logic, 2003Over some particular rings (for example, over the ring of integers, \(\mathbb{Z }\)) the main logical relations (disjunctions, conjunctions and negations) of polynomial equations admit Diophantine definitions. The main contribution of this paper is to investigate the Diophantine definability of these relations over an arbitrary finite commutative ring ...

Properties of commutative transformations of data models
Cybernetics, 1986The data model (DM) is a formalism that makes it possible to present the states and dynamics of subject domains in data bases. In data base management systems (DBMS), DM is defined by a combination of the language means of data definitions (LMDD) and data manipulation (LMDM).

The discrete commutator property of approximation spaces
Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 1999Summary: We prove a super approximation result for a wide class of approximation spaces (including finite elements and wavelet type spaces). In particular such property, also referred at as the discrete commutator property holds, provided that a projector operator exists, who acts ``locally''.

Two commutativity properties for rings
2016Let A be a nonempty subset of the ring R, and let n be a fixed positive integer. We call R a Q(n)-ring if \(n[x,y]=0\) implies \([x,y]=0\); we say that R has property (II-A) if for each x,y\(\in R\) such that x-y\(\in A\), either \(x^ 2=y^ 2\) or x and y both centralize A.
