On the divisibility of binomial coefficients

open access: yesArs Mathematica Contemporanea, 2020
In Pacific J. Math. 292 (2018), 223-238, Shareshian and Woodroofe asked if for every positive integer $n$ there exist primes $p$ and $q$ such that, for all integers $k$ with $1 \leq k \leq n-1$, the binomial coefficient $\binom{n}{k}$ is divisible by at least one of $p$ or $q$. We give conditions under which a number $n$ has this property and discuss a

On Binomial Coefficient Residues [PDF]

open access: yesCanadian Journal of Mathematics, 1957
The number of binomial coefficients , which are congruent to j , 0 ≤ j ≤ p − 1, modulo the prime number p is denoted by θj(n). In this paper we give systems of simultaneous linear difference equations with constant coefficients whose

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 ...

Poset binomials and rainbow characters [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
This paper introduces a variation on the binomial coefficient that depends on a poset and interpolates between $q$-binomials and 1-binomials: a total order gives the usual $q$-binomial, and a poset with no relations gives the usual binomial coefficient ...

A sum of binomial coefficients [PDF]

open access: yesMathematics of Computation, 1978
An explicit expression is derived for the sum of the ( k + 1 ) (k + 1) st binomial coefficients in the nth, ( n − m ) (n - m) th, ( n − 2 m ) (n - 2m) th,... row of the arithmetic triangle.

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

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 ...

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)!}.
