Why Does the Slope Definition of Work?: A Self-Contained Exploration After Real Analysis
Hung Viet Chu, Steven J. Miller, Joshua M. Siktar
Euler's number is often introduced through compound interest, an infinite series, an area, or the slope of an exponential function. The last viewpoint is especially attractive:…
Generalizing a Pair of Diophantine Equations
Hung Viet Chu, Dongho Kim, Theodore Koch +2
For coprime integers and , it is known that exactly one of the two Diophantine equations $$ ax+by\ =\ \frac{(a-1)(b-1)}{2} \qquad\text{and}\qquad 1+ax+by\ =\ \frac{(a-1)(b-1…
Counting Schreier Sets Under Neighborhood Conditions
Ben Chen, Hung Viet Chu, Corbin F. Foss +4
We count Schreier sets that satisfy a neighborhood condition, including -clustered, -consecutive-free, -neighbored, -isolated, and closed under integral -averages. F…
On Zeckendorf-Niven numbers and arithmetic progressions
Kelly Lao, Steven J. Miller, Nicholas Rosa +4
A positive integer is Zeckendorf-Niven (respectively, Lucas-Niven) if it is divisible by the number of summands in its Zeckendorf decomposition (respectively, Lucas decomposition).…
Problems Regarding a Pair of Diophantine Equations
Hung Viet Chu, Steven J. Miller, Garrett Tresch
For two relatively prime positive integers , it is known that exactly one of the two Diophantine equations $$ax + by \ =\ \frac{(a-1)(b-1)}{2}\ \mbox{ and }\ 1…
On a Roll Again: Analysis of a Dice Removal Game
Francesco Camellini, Wissam Ghantous, Andrea M. Lanocita +4
Suppose we have dice, each with faces (assume ). On the first turn, roll all of them, and remove from play those that rolled an . Roll all of the remaining dice…
A Pair of Diophantine Equations and Fibonacci-Like Sequences
Hung Viet Chu, Rishabh Gulecha, Sicheng Guo +3
Given two relatively prime numbers and , it is known that exactly one of the two Diophantine equations has a nonnegative integral solution : $$ ax + by \ =\ \frac{(a-…
Linear Recurrences from Counting Schreier-Type Multisets
Hung Viet Chu, Yubo Geng, Julian King +3
A nonempty set is Schreier if . Bird observed that counting Schreier sets in a certain way produces the Fibonacci sequence. Since then, various connections betwe…
Composite Numbers in an Arithmetic Progression
Hung Viet Chu, Steven J. Miller, Joshua M. Siktar
One challenge (or opportunity!) that many instructors face is how varied the backgrounds, abilities, and interests of students are. In order to simultaneously instill confidence in…
A Pair of Diophantine Equations Involving the Fibonacci Numbers
Xuyuan Chen, Hung Viet Chu, Fadhlannafis K. Kesumajana +5
Let be relatively prime. Previous work showed that exactly one of the two equations and has a nonnegative…
Sum of Consecutive Terms of Pell and Related Sequences
Navvye Anand, Amit Kumar Basistha, Kenny B. Davenport +4
We study new identities related to the sums of adjacent terms in the Pell sequence, defined by for and , and generalize the…
On a Pair of Diophantine Equations
Sujith Uthsara Kalansuriya Arachchi, Hung Viet Chu, Jiasen Liu +3
For relatively prime natural numbers and , we study the two equations and , which arise from the study of cyclotomic polynomial…
