Homotopy equivalence of digital pictures in

Dae-Woong Lee, P. Christopher Staecker

We investigate the properties of digital homotopy in the context of digital pictures , where is a finite set, is an adjacency relation on ,…

The Face Group of a Simplicial Complex

Gregory Lupton, Nicholas A. Scoville, P. Christopher Staecker

The edge group of a simplicial complex is a well-known, combinatorial version of the fundamental group. It is a group associated to a simplicial complex that consists of equivalenc…

At most n-valued maps

Daciberg Lima Goncalves, Robert Skiba, P. Christopher Staecker

This paper concerns various models of ``at-most--valued maps''. That is, multivalued maps for which has cardinality at most for each . We consider…

On digital H-spaces

Wayne A. Johnson, Dae-Woong Lee, P. Christopher Staecker

In this article, we investigate properties of digital H-spaces in the graph theoretic model of digital topology. As in prior work, the results obtained often depend fundamentally o…

Ahead of the Count: An Algorithm for Probabilistic Prediction of Instant Runoff (IRV) Elections

Nicholas Kapoor, P. Christopher Staecker

How can we probabilistically predict the winner in a ranked-choice election without all ballots being counted? In this study, we introduce a novel algorithm designed to predict out…

Digital topological groups

Dae-Woong Lee, P. Christopher Staecker

In this article, we develop the basic theory of digital topological groups. The basic definitions directly lead to two separate categories, based on the details of the continuity r…
