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…
