One-way infinite 2-walks in planar graphs

Daniel P. Biebighauser, M. N. Ellingham

We prove that every 3-connected 2-indivisible infinite planar graph has a 1-way infinite 2-walk. (A graph is 2-indivisible if deleting finitely many vertices leaves at most one inf…

Partial duality and closed 2-cell embeddings

M. N. Ellingham, Xiaoya Zha

In 2009 Chmutov introduced the idea of partial duality for embeddings of graphs in surfaces. We discuss some alternative descriptions of partial duality, which demonstrate the symm…
