On SierpiÅski and Riesel Repdigits and Repintegers

Chris Bispels, Matthew Cohen, Joshua Harrington +4

For positive integers $b \geq 2$ , $k < b$ , and $t$ , we say that an integer $k_{b}^{(t)}$ is a $b$ -repdigit if $k_{b}^{(t)}$ can be expressed as the digit $k$ repeated $t$ times in base-$b…

A further investigation on covering systems with odd moduli

Chris Bispels, Matthew Cohen, Joshua Harrington +4

ErdÅs first introduced the idea of covering systems in 1950. Since then, much of the work in this area has concentrated on identifying covering systems that meet specific conditio…

Generalized results on the convergence of Thue-Morse turtle curves

Leif Schaumann

Work by Ma and Holdener in 2005 revealed that using turtle graphics to visualize the Thue-Morse sequence can result in curves which approximate the Koch fractal curve. A 2007 paper…

Bounds on the mosaic number of Legendrian Knots

Margaret Kipe, Samantha Pezzimenti, Leif Schaumann +2

Mosaic tiles were first introduced by Lomonaco and Kauffman in 2008 to describe quantum knots, and have since been studied for their own right. Using a modified set of tiles, front…
