Alice and Bob take turns to collect chips in the following manner. In each turn, Alice tosses a fair coin, which decides whether she collects a or b chips, where a and b are positive integers. If Alice collects a chips, then Bob collects b chips, and

An ordered triple $(s,p,n)$ is called admissible if there exist two different multisets $X=\{x_1,x_2,\dotsc,x_n\}$ and $Y=\{y_1,y_2,\dotsc,y_n\}$ such that $X$ and $Y$ share the same sum $s$, the same product $p$, and the same size $n$. We first coun

A positive integer n is a super totient number if the set of positive integers less than n and relatively prime to n can be partitioned into two sets of equal sum. In this article, we give a complete classification of super totient numbers. We also u

We consider integer matrices Nt whose rows are indexed by the t-subsets of an n-set and whose columns are all distinct images of a particular column under the symmetric group Sn. Examples include matrices in the association algebras of the Johnson sc

Given an ordered triple of positive integers ( n , r , b ) , where 1 ≤ b ≤ n r , does there exist a matrix of size r × n with exactly b invertible submatrices of size r × r ? Such a matrix is called an ( n , r , b ) -matrix. This question is a

Relative BPS state counts for log Calabi-Yau surface pairs were introduced by Gross-Pandharipande-Siebert and conjectured by the authors to be integers. For toric Del Pezzo surfaces, we provide an arithmetic proof of this conjecture, by relating thes
