A Linear-Time Algorithm for Finding a Maximal Planar Subgraph

In this paper we study the acyclic 3-colorability of some subclasses of planar graphs. First, we show that there exist infinite classes of cubic planar graphs that are not acyclically 3-colorable. Then, we show that every planar graph has a subdivision ...

MacGillivary and Seyffarth [G. MacGillivray, K. Seyffarth, Domination numbers of planar graphs, J. Graph Theory 22 (1996) 213-229] proved that planar graphs of diameter two have domination number at most three. Goddard and Henning [W. Goddard, M.A. ...

Let G=(V,E) be a graph. A proper vertex coloring of G is acyclic if G contains no bicolored cycle. Namely, every cycle of G must be colored with at least three colors. G is acyclically L-list colorable if for a given list assignment L={L(v):v@?V}, there ...
