The Subpower Membership Problem for Finite Algebras with Cube Terms [PDF]

open access: greenLogical Methods in Computer Science, 2019
The subalgebra membership problem is the problem of deciding if a given element belongs to an algebra given by a set of generators. This is one of the best established computational problems in algebra.

Associative Ternary Algebras and Ternary Lie Algebras at Cube Roots of Unity

open access: goldMathematics
We propose an approach to extend the concept of a Lie algebra to ternary structures based on ω-symmetry, where ω is a primitive cube root of unity. We give a definition of a corresponding structure, called a ternary Lie algebra at cube roots of unity, or

Poincaré type inequalities on the discrete cube and in the CAR algebra [PDF]

open access: greenProbability Theory and Related Fields, 2007
We prove Lp Poincaré inequalities with suitable dimension free constants for functions on the discrete cube {−1, 1}n. As well known, such inequalities for p an even integer allow to recover an exponential inequality hence the concentration phenomenon ...

Initial Optimization Techniques for the Cube Algebra Query Language

open access: diamondInternational Journal of Data Warehousing and Mining, 2022
A common model used in addressing today's overwhelming amounts of data is the OLAP Cube. The OLAP community has proposed several cube algebras, although a standard has still not been nominated. This study focuses on a recent addition to the cube algebras:

A Cube Algebra with Comparative Operations: Containment, Overlap, Distance and Usability [PDF]

open access: greenarXiv.org, 2022
In this paper, we provide a comprehensive rigorous modeling for multidimensional spaces with hierarchically structured dimensions in several layers of abstractions and data cubes that live in such spaces.

Ternary Associativity and Ternary Lie Algebras at Cube Roots of Unity [PDF]

open access: yesAxioms
We propose a new approach to extend the notion of commutator and Lie algebra to algebras with ternary multiplication laws. Our approach is based on the ternary associativity of the first and second kinds.

The data cube as a typed linear algebra operator [PDF]

open access: goldProceedings of The 16th International Symposium on Database Programming Languages, 2017
There is a need for a typed notation for linear algebra applicable to the fields of econometrics and data mining. In this paper we show that such a notation exists and can be useful in formalizing and reasoning about data aggregation operations.One such operation - the construction of a data cube - is shown to be easily expressible as a linear algebra ...

A convergence on Boolean algebras generalizing the convergence on the Aleksandrov cube [PDF]

open access: green, 2013
We compare the forcing related properties of a complete Boolean algebra B with the properties of the convergences $\lambda_s$ (the algebraic convergence) and $\lambda_{ls}$ on B generalizing the convergence on the Cantor and Aleksandrov cube respectively.

Naturally dualizable algebras omitting types 1 and 5 have a cube term

open access: yesAlgebra Universalis, 2015
An early result in the theory of Natural Dualities is that an algebra with a near unanimity (NU) term is dualizable. A converse to this is also true: if V(A) is congruence distributive and A is dualizable, then A has an NU term.

The number of two-term tilting complexes over symmetric algebras with radical cube zero [PDF]

open access: greenAnnals of Combinatorics, 2018
In this paper, we compute the number of two-term tilting complexes for an arbitrary symmetric algebra with radical cube zero over an algebraically closed field.
