Additive Coloring of Planar Graphs
- MathematicsGraphs Comb.
- 2014
It is proved thateta (G)⩽468 for every planar graph G and that for each r-chromatic graph Gr with no additive coloring by elements of any abelian group of order r, the minimum number k is denoted byη(G) .

Deciding first-order properties of nowhere dense graphs
- Mathematics, Computer ScienceSTOC
- 2014
It is shown that deciding properties of graphs definable in first-order logic is fixed-parameter tractable on nowhere dense graph classes, and a "rank-preserving" version of Gaifman's locality theorem is proved.
The point-arboricity of a graph
- Mathematics
- 1968
The point-arboricity ρ(G) of a graphG is defined as the minimum number of subsets in a partition of the point set ofG so that each subset induces an acyclic subgraph. Dually, the tuleity τ(G) is the…

An inequality involving the vertex arboricity and edge arboricity of a graph
- MathematicsJ. Graph Theory
- 1986
The inequality a(G) ⩽ a1 (G) is proved, and this is sharp, and two related inequalities, involving another parameter, are also proved.
