Generalized Chebyshev Polynomials
Journal Title: Discussiones Mathematicae - General Algebra and Applications - Year 2018, Vol 38, Issue 1
Abstract
Let h(x) be a non constant polynomial with rational coefficients. Our aim is to introduce the h(x)-Chebyshev polynomials of the first and second kind Tn and Un. We show that they are in a Q-vectorial subspace En(x) of Q [x] of dimension n. We establish that the polynomial sequences (h kTn−k)k and (h kUn−k)k, (0 ≤ k ≤ n − 1) are two bases of En(x) for which Tn and Un admit remarkable integer coordinates.

Sublattices corresponding to very true operators in commutative basic algebras
We introduce the concept of very true operator on a commutative basic algebra in a way analogous to that for fuzzy logics. We are motivated by the fact that commutative basic algebras form an algebraic axiomatization of...
A Note on Additive Groups of Some Specific Torsion-Free Rings of Rank Three and Mixed Associative Rings
It is studied how rank two pure subgroups of a torsion-free Abelian group of rank three influences its structure and type set. In particular, the criterion for such a subgroup B to be a direct summand of a torsion-free A...
BI-INTERIOR IDEALS OF Γ-SEMIRINGS
In this paper, as a further generalization of ideals, we introduce the notion of bi-interior ideal as a generalization of quasi ideal, bi-ideal and interior ideal of Γ-semiring and study the properties of bi-interior ide...
SYMMETRIC BI-DERIVATIONS IN ALMOST DISTRIBUTIVE LATTICES
In this paper, we introduce the concept of symmetric bi-derivation in an Almost Distributive Lattice (ADL) and derive some important properties of symmetric bi-derivations in ADLs.
ON THE GENUS OF THE CAYLEY GRAPH OF A COMMUTATIVE RING
Let R be a commutative ring with non-zero identity and let Z(R) be the set of all zero-divisors. The Cayley graph CAY(R) of R is the simple undirected graph whose vertices are elements of R and two distinct vertices x an...
