Abstract
We provide a new method for extending results on finite planar graphs to the infinite case. Thus a result of Ungar on finite graphs has the following extension: Every infinite, planar, cubic, cyclically 4โedgeโconnected graph has a representation in the plane such that every edge is a horizontal or vertical straight line segment, and such that no two edges cross. A result of Tamassia and Tollis extends as follows: Every countably infinite planar graph is a subgraph of a visibility graph. Furthermore, every locally finite, 2โconnected, planar graph is a visibility graph. ยฉ 2006 Wiley Periodicals, Inc. J Graph Theory 52: 257โ265, 2006

## Abstract We prove NashโWilliams' conjecture that every 4โconnected, 3โindivisible, infinite, planar graph contains a spanning 2โway infinite path. A graph is said to be 3โindivisible if the deletion of any finite set of vertices results in at most two infinite components. ยฉ 2007 Wiley Periodical
An infinite graph is 2-indivisible if the deletion of any finite set of vertices from the graph results in exactly one infinite component. Let G be a 4-connected, 2-indivisible, infinite, plane graph. It is known that G contains a spanning 1-way infinite path. In this paper, we prove a stronger resu
