Problems for combinatorial numbers satisfying a class of triangular arrays

open access: yesLietuvos Matematikos Rinkinys, 2023
Numbers satisfying a class of triangular arrays, defined by a bivariate first-order linear difference equation with linear coefficients, include a wide range of combinatorial numbers: binomial coefficients, Morgan numbers, Stirling numbers of the first ...

A central limit theorem for numbers satisfying a class of triangular arrays associated with Hermite polynomials

open access: yesLietuvos Matematikos Rinkinys, 2021
The paper extends the investigations of limit theorems for numbers satisfying a class of triangular arrays. We obtain analytical expressions for the semiexponential generating function the numbers, associated with Hermite polynomials.

Some Algebraic Aspects of MorseCode Sequences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Morse code sequences are very useful to give combinatorial interpretations of various properties of Fibonacci numbers. In this note we study some algebraic and combinatorial aspects of Morse code sequences and obtain several q-analogues of Fibonacci

SOME NATURAL PHENOMENA AND SIGN COMBINATORIAL SPACES

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики", 2020
The literature describes many natural phenomena associated with combinatorial numbers, including the «gold» number that is represented by Fibonacci numbers. This suggests that the laws of combinatorics are inherent in nature.

Remixed Eulerian numbers

open access: yesForum of Mathematics, Sigma, 2023
Remixed Eulerian numbers are a polynomial q-deformation of Postnikov’s mixed Eulerian numbers. They arose naturally in previous work by the authors concerning the permutahedral variety and subsume well-known families of polynomials such as q-binomial ...

Combinatorial Models of the Distribution of Prime Numbers

open access: yesMathematics, 2021
This work is divided into two parts. In the first one, the combinatorics of a new class of randomly generated objects, exhibiting the same properties as the distribution of prime numbers, is solved and the probability distribution of the combinatorial ...

Mixed volumes of hypersimplices [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
In this extended abstract we consider mixed volumes of combinations of hypersimplices. These numbers, called mixed Eulerian numbers, were first considered by A.

New combinatorial proof of the multiple binomial coefficient identity

open access: yesVojnotehnički Glasnik, 2022
Introduction/purpose: In this paper a new combinatorial proof of an already existing multiple sum with multiple binomial coefficients is given. The derived identity is related to the Fibonacci numbers. Methods: Combinatorial reasoning is used to obtain

A Combinatorial Model for $q$-Generalized Stirling and Bell Numbers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We describe a combinatorial model for the $q$-analogs of the generalized Stirling numbers in terms of bugs and colonies. Using both algebraic and combinatorial methods, we derive explicit formulas, recursions and generating functions for these $q ...

On Fibonacci (k,p)-Numbers and Their Interpretations

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
In this paper, we define new kinds of Fibonacci numbers, which generalize both Fibonacci, Jacobsthal, Narayana numbers and Fibonacci p-numbers in the distance sense, using the definition of a distance between numbers by a recurrence relation according to
