Practical numbers among the binomial coefficients [PDF]

open access: yes, 2020
A practical number is a positive integer n such that every positive integer less than n can be written as a sum of distinct divisors of n. We prove that most of the binomial coefficients are practical numbers. Precisely, letting f(n) denote the number of

Sums of Reciprocals of Triple Binomial Coefficients

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We investigate the integral representation of infinite sums involving the reciprocals of triple binomial coefficients. We also recover some wellknown properties of 𝜁(3) and extend the range of results given by other authors.

On some series involving the binomial coefficients $binom{3n}{n}$ [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Using a simple transformation, we obtain much simpler forms for some series involving binomial coefficients $binom{3n}{n}$ derived by Necdet Batir. New evaluations are given and connections with Fibonacci numbers and the golden ratio are established ...

Binomial coefficients and their visualization [PDF]

open access: yes, 2019
In this paper, the authors present some of the results achieved by mathematicians who belonged to different cultures and lived in different time periods, but were engaged in determining (formula for determining) binomial coefficients.

Ray trajectories, binomial coefficients of a new type, and the binary system [PDF]

open access: yesКомпьютерные исследования и моделирование, 2010
The paper describes a new algorithm of construction of the nonlinear arithmetic triangle on the basis of numerical simulation and the binary system. It demonstrates that the numbers that fill the nonlinear arithmetic triangle may be binomial coefficients

Inequalities for Binomial Coefficients

open access: yesJournal of Mathematical Analysis and Applications, 1999
For any real number \(r\) with \(r>1\), let \(c_r= (2\pi(1-{1\over r}))^{-1/2}\) and \(d_r= (r-1)/(1-{1\over r})^r\). Let \(B_{2m}\) \((m= 1,2,\dots)\) be the Bernoulli numbers defined by \[ {z\over e^z-1}=1-{z\over 2}+\sum^\infty_{m=1} B_{2m}{z^{2m}\over (2m)!}.

Plane Partitions and a Problem of Josephus

open access: yesMathematics, 2023
The Josephus Problem is a mathematical counting-out problem with a grim description: given a group of n persons arranged in a circle under the edict that every kth person will be executed going around the circle until only one remains, find the position ...

A generalization of the binomial coefficients

open access: yesDiscrete Mathematics, 1992
We pose the question of what is the best generalization of the factorial and the binomial coefficient. We give several examples, derive their combinatorial properties, and demonstrate their interrelationships. On cherche ici à déterminer est la meilleure généralisation possible des factorielles et des coefficients du binôome. On s'interesse à plusieurs
