Generalizations of a Curious Family of MSTD Sets Hidden By Interior Blocks

Hung Viet Chu, Noah Luntzlara, Steven J. Miller +1

A set $A$ is MSTD (more-sum-than-difference) or sum-dominant if $∣ A + A ∣ > ∣ A - A ∣$ , and is RSD (restricted-sum dominant) if $∣ A +^A ∣ > ∣ A - A ∣$ , where $A +^A$ is the set of sums of…

Infinite Families of Partitions into MSTD Subsets

Hung Viet Chu, Noah Luntzlara, Steven J. Miller +1

A set $A$ is MSTD (more-sum-than-difference) if $∣ A + A ∣ > ∣ A - A ∣$ . Though MSTD sets are rare, Martin and O'Bryant proved that there exists a positive constant lower bound for the propo…

Folded ribbon knots in the plane

Elizabeth Denne

This survey reviews Kauffman's model of folded ribbon knots: knots made of a thin strip of paper folded flat in the plane. The ribbonlength is the length to width ratio of such a r…

Period sets of linear recurrences over finite fields and related commutative rings

Michael R. Bush, Danjoseph Quijada

After giving an overview of the existing theory regarding the periods of sequences defined by linear recurrences over finite fields, we give explicit descriptions of the sets of pe…

The $μ$ -permanent revisited

Carlos M. da Fonseca

Let $A = (a_{ij})$ be an $n$ -by- $n$ matrix. For any real number $μ$ , we define the polynomial $P_{μ} (A) = σ \in S_{n} \sum a_{1 σ (1)} \dots a_{nσ (n)} μ^{ℓ (σ)},$ as the $μ$ -permane…

Finite subgroups of the extended modular group

Gregory Dresden, Prakriti Panthi, Anukriti Shrestha +1

We show that in the extended modular group PGL(2,Z) there are exactly seven finite subgroups up to conjugacy; three subgroups of size 2, one subgroup each of size 3, 4, and 6, and…
