Discrete homotopy of token configurations

Bob Lutz

This paper studies graphical analogs of symmetric products and unordered configuration spaces in topology. We do so from the perspective of the discrete homotopy theory introduced…

Higher discrete homotopy groups of graphs

Bob Lutz

This paper studies a discrete homotopy theory for graphs introduced by Barcelo et al. We prove two main results. First we show that if is a graph containing no 3- or 4-cycles,…
