Some New Families of Finite Orthogonal Polynomials in Two Variables

open access: yesAxioms, 2023
In this paper, we generalize the study of finite sequences of orthogonal polynomials from one to two variables. In doing so, twenty three new classes of bivariate finite orthogonal polynomials are presented, obtained from the product of a finite and an ...

The mathematics of generalized Fibonacci sequences: Binet's formula and identities [PDF]

open access: yesMathematica Moravica
This article considers a generalized Fibonacci sequence {Vn} with general initial conditions, V0 = a, V1 = b, and a versatile recurrence relation Vn = pVn-1 + qVn-2, where n ≥ 2 and a, b, p and q are any non-zero real numbers. The generating function and

Floor and ceiling functions for Pell numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The analytical study of the Pell number and the role of floor and ceiling functions into their computation is examined. Closed expressions of Pell numbers were initially derived using Binet's formula, followed by an asymptotic behavior study of the ...

Asymptotic series solution of variational stokes problems in planar domain with crack-like singularity

open access: yesApplied Mathematics in Science and Engineering, 2022
A class of nonlinear variational problems describing incompressible fluids and solids by stationary Stokes equations given in a planar domain with a crack (infinitely thin flat plate in fluids) is considered.

Towards the Centenary of Sheffer Polynomial Sequences: Old and Recent Results

open access: yesMathematics, 2022
Sheffer’s work is about to turn 100 years after its publication. In reporting this important event, we recall some interesting old and recent results, aware of the incompleteness of the wide existing literature. Particularly, we recall Sheffer’s approach,

Recurrence relations connecting mock theta functions and restricted partition functions [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper, we provide some recurrence relations connecting restricted partition functions and mock theta functions. Elementary manipulations are used including Jacobi triple product identity, Euler's pentagonal number theorem, and Ramanujan's theta ...

On fourth-order jacobsthal quaternions

open access: yesJournal of Mathematical Sciences and Modelling, 2018
In this paper, we present for the first time a sequence of quaternions of order 4 that we will call the fourth-order Jacobsthal and the fourth-order Jacobsthal-Lucas quaternions. In particular, we are interested in the generating function, Binet formula,
