Irreducibility over the Max-Min Semiring

Benjamin Baily, Justine Dell, Henry L. Fleischmann +4

For sets $A, B \subset N$ , their sumset is $A + B := {a + b : a \in A, b \in B}$ . If we cannot write a set $C$ as $C = A + B$ with $∣ A ∣, ∣ B ∣ \geq 2$ , then we say that $C$ is $\tex…

Distinct Angle Problems and Variants

Henry L. Fleischmann, Hongyi B. Hu, Faye Jackson +4

The Erdős distinct distance problem is a ubiquitous problem in discrete geometry. Less well known is Erdős' distinct angle problem, the problem of finding the minimum number of dis…

Optimal Point Sets Determining Few Distinct Angles

Henry L. Fleischmann, Steven J. Miller, Eyvindur A. Palsson +2

We characterize the largest point sets in the plane which define at most 1, 2, and 3 angles. For $P (k)$ the largest size of a point set admitting at most $k$ angles, we prove $P(2)…
