In 1966 Barnette introduced a set of graphs, called circuit graphs, which are obtained from 3-connected planar graphs by deleting a vertex. Circuit graphs and 3-connected planar g...

In 1988, Seiya Negami published a conjecture stating that a graph G has a finite planar cover (i.e. a homomorphism from some planar graph onto G which maps the vertex neighbourhoo...

We investigate the computability of countable subshifts in one dimension, and their members. Subshifts of Cantor-Bendixson rank one contain only eventually periodic elements. Any ...
