摘要
A graph is pseudo-outerplanar if each of its blocks has an embedding in the plane so that the vertices lie on a fixed circle and the edges lie inside the disk of this circle with each of them crossing at most one another. It is proved that every pseudo-outerplanar graph with maximum degree Delta >= 5 is totally (Delta + 1)-choosable. (C) 2013 Elsevier B.V. All rights reserved.
