Topological realizations and fundamental groups of higher-rank graphs
S. Kaliszewski, Alex Kumjian, John Quigg +1
We investigate topological realizations of higher-rank graphs. We show that the fundamental group of a higher-rank graph coincides with the fundamental group of its topological rea…

1-Overlap Cycles for Steiner Triple Systems
Victoria Horan, Glenn Hurlbert
A number of applications of Steiner triple systems (e.g. disk erasure codes) exist that require a special ordering of its blocks. Universal cycles, introduced by Chung, Diaconis, a…
