چکیده
The equitable tree-coloring can formulate a structure decomposition problem on the communication network with some security considerations. Namely, an tree-k-coloring of graph is vertex coloring using k distinct colors such that every color class induces forest and sizes any two classes differ by at most one. In this paper, we show theoretical results graphs proving d-degenerate maximum degree ? equitably tree-k-colorable for integer ? (? + 1)/2 provided 9.818d, confirming arboricity conjecture low degeneracy.

A conjecture on equitable vertex arboricity of graphs
Wu, Zhang and Li [4] conjectured that the set of vertices of any simple graph G can be equitably partitioned into ⌈(∆(G) + 1)/2⌉ subsets so that each of them induces a forest of G. In this note, we prove this conjecture for graphs G with ∆(G) ≥ |G|/2.
متن کاملEquitable vertex arboricity of graphs
An equitable (t, k, d)-tree-coloring of a graph G is a coloring to vertices of G such that the sizes of any two color classes differ by at most one and the subgraph induced by each color class is a forest of maximum degree at most k and diameter at most d. The minimum t such that G has an equitable (t′, k, d)-tree-coloring for every t′ ≥ t is called the strong equitable (k, d)-vertex-arboricity...
متن کاملEquitable vertex arboricity of planar graphs
Let G1 be a planar graph such that all cycles of length at most 4 are independent and let G2 be a planar graph without 3-cycles and adjacent 4-cycles. It is proved that the set of vertices of G1 and G2 can be equitably partitioned into t subsets for every t ≥ 3 so that each subset induces a forest. These results partially confirm a conjecture of Wu, Zhang
متن کاملEquitable list point arboricity of graphs
A graph G is list point k-arborable if, whenever we are given a k-list assignment L(v) of colors for each vertex v ∈ V(G), we can choose a color c(v) ∈ L(v) for each vertex v so that each color class induces an acyclic subgraph of G, and is equitable list point k-arborable if G is list point k-arborable and each color appears on at most ⌈|V(G)|/k⌉ vertices of G. In this paper, we conjecture tha...
متن کاملOn the vertex-arboricity of planar graphs
The vertex-arboricity a(G) of a graph G is the minimum number of subsets into which the set of vertices of G can be partitioned so that each subset induces a forest. It is well-known that a(G) ≤ 3 for any planar graph G. In this paper we prove that a(G) ≤ 2 whenever G is planar and either G has no 4-cycles or any two triangles of G are at distance at least 3. c © 2007 Elsevier Ltd. All rights r...
