Tilting modules over Auslander algebras of Nakayama algebras with radical cube zero

International Journal of Algebra and Computation, 2020
Let A′ be the Auslander algebra of a finite dimensional basic connected Nakayama algebra A with radical cube zero and n simple modules. Then the cardinality #tiltA′ of the set consisting of isomorphism classes of basic tilting A′-modules is #tiltA′ = 

Cube Algebra: A Generic User-Centric Model and Query Language for OLAP Cubes

International Journal of Data Warehousing and Mining, 2013
The lack of an appropriate conceptual model for data warehouses and OLAP systems has led to the tendency to deploy logical models (for example, star, snowflake, and constellation schemas) for them as conceptual models. ER model extensions, UML extensions, special graphical user interfaces, and dashboards have been proposed as conceptual approaches ...

Existence of cube terms in finite algebras [PDF]

open access: yesAlgebra universalis, 2021
We study the problem of whether a given finite algebra with finitely many basic operations contains a cube term; we give both structural and algorithmic results. We show that if such an algebra has a cube term then it has a cube term of dimension at most $N$, where the number $N$ depends on the arities of basic operations of the algebra and the size of

Seeing Algebraic Structure: The Rubik's Cube

Mathematics Teacher: Learning and Teaching PK-12, 2020
Few high school students associate mathematics with playfulness. In this paper, we offer a series of lessons focused on the underlying algebraic structures of the Rubik's Cube. The Rubik's Cube offers students an interesting space to enjoy the playful side of mathematics, while appreciating mathematics otherwise lost in routine experiences.
