Connection between binomial coefficients and their analogs and symmetric functions

A Bazeniar, M Ahmia… - Turkish Journal of …, 2018 - journals.tubitak.gov.tr
In this paper, on one hand, we propose a new type of symmetric function to interpret the bi
$^{s} $ nomial coefficients and their analogs. On other hand, according to this function, we …

[PDF][PDF] Power sums in hyperbolic Pascal triangles

L Németh, L Szalay - Analele ştiinţifice ale Universităţii" Ovidius" …, 2018 - sciendo.com
In this paper, we describe a method to determine the power sum of the elements of the rows
in the hyperbolic Pascal triangles corresponding to {4, q} with q≥ 5. The method is based on …

Decomposition method related to saturated hyperball packings

J Szirmai - arXiv preprint arXiv:1709.04369, 2017 - arxiv.org
In this paper we study the problem of hyperball (hypersphere) packings in $3 $-dimensional
hyperbolic space. We introduce a new definition of the non-compact saturated ball packings …

H Belbachir, A Mehdaoui, L Szalay - Journal of Combinatorial Theory …, 2019 - Elsevier
In this paper, we describe the recurrence relation associated to the sum of diagonal
elements lying along a finite ray of certain type crossing the three-dimensional Pascal …

Hyperball packings related to truncated cube and octahedron tilings in hyperbolic space

J Szirmai - Contributions to Discrete Mathematics, 2020 - cdm.ucalgary.ca
In this paper, we study congruent and noncongruent hyperball (hypersphere) packings to
the truncated regular cube and octahedron tilings. These are derived from the Coxeter …

Pascal pyramid in the space xR

L Németh - Mathematical Communications, 2017 - hrcak.srce.hr
Sažetak In this article we introduce a new type of Pascal pyramids. A regular squared
mosaic in the hyperbolic plane yields an\(h^{2} r\)-cube mosaic in space\(H^{2}\) xR and the …

A generalization of the hyperbolic Pascal pyramid

H Belbachir, F Rami, L Németh, L Szalay - Indian Journal of Pure and …, 2023 - Springer
In the present paper, we consider a variation of the hyperbolic Pascal pyramid where the
three leg-sequences (the constant 1 sequence) are replaced by the sequences {α n} n≥ …

[PDF][PDF] Hyperbolic Pascal simplex

L Németh - International Electronic Journal of Geometry, 2017 - dergipark.org.tr
In this article we introduce a new geometric object called hyperbolic Pascal simplex. This
newobject is presented by the regular hypercube mosaic in the 4-dimensional hyperbolic …

Properties of hyperbolic Pascal triangles

H Belbachir, L Németh… - … on Mathematics: Pure …, 2017 - ui.adsabs.harvard.edu
Here we summarize some results on a recently introduced new generalization of Pascal's
triangle called hyperbolic Pascal triangles. The name comes from the mathematical …

Hyperball packings related to octahedron and cube tilings in hyperbolic space
