Small $q$ -kernels in digraphs with minimum in-degree $I^´$

Geoffrey Boyer, Matt Burnham, Daniela ÄernÃ¡ +5

For a digraph $D$ , a subset $Q \subseteq V (D)$ is called a $q$ -kernel if $Q$ is an independent set and all vertices in $V (D)$ are reachable from $Q$ via a directed path of length at…

Schuttes property for sets of tournaments and an application to dice games

Joel Jeffries

A tournament has Schuttes property $S_{k}$ if for every set of $k$ vertices, there is a vertex which dominates the set. In 1963, Erdos provided bounds for $f (k)$ , the smallest order…

Enumerating Prime Patterns in Juggling Variations

Steve Butler, Vera Choi, Joel Jeffries +3

Juggling patterns can be mathematically modeled as closed walks within directed state graphs. In this paper, we present a unified framework of unbounded juggling patterns and its v…
