Cofinite Graphs and their Profinite Completions
Amrita Acharyya, Jon M. Corson, Bikash Das
We generalize the idea of cofinite groups, due to B. Hartley. First we define cofinite spaces in general. Then, as a special situation, we study cofinite graphs and their uniform c…

Cofinite Connectedness and Cofinite Group Actions
Amrita Acharyya, Jon M. Corson, Bikash Das
We have defined and established a theory of cofinite connectedness of a cofinite graph. Many of the properties of connectedness of topological spaces have analogs for cofinite conn…
