چکیده
Assume G is a graph, and k,d,m are natural numbers. The d-defective (k,m)-painting game on played by two players: Lister Painter. Initially, each vertex has k tokens uncolored. In round, chooses set M of vertices removes one token from chosen vertex. Painter colors subset X which induces subgraph G[X] maximum degree at most d. A v fully colored if received m colors. wins the end some there with no more left not colored. Otherwise, all wins. We say (k,m)-paintable winning strategy in this game. prove that every planar graph 1-defective (9,2)-paintable. addition, our also implies (⌈92m⌉,m)-paintable for any positive m.

Every toroidal graph without adjacent triangles is (4, 1)*-choosable
In this paper, a structural theorem about toroidal graphs is given that strengthens a result of Borodin on plane graphs. As a consequence, it is proved that every toroidal graph without adjacent triangles is (4, 1)∗-choosable. This result is best possible in the sense that K7 is a non-(3, 1)∗-choosable toroidal graph. A linear time algorithm for producing such a coloring is presented also. © 20...
متن کاملEvery planar graph without cycles of lengths 4 to 12 is acyclically 3-choosable
An acyclic coloring of a graph G is a coloring of its vertices such that : (i) no two adjacent vertices in G receive the same color and (ii) no bicolored cycles exist in G. A list assignment of G is a function L that assigns to each vertex v ∈ V (G) a list L(v) of available colors. Let G be a graph and L be a list assignment of G. The graph G is acyclically L-list colorable if there exists an a...
متن کامل2 01 0 Every planar graph without adjacent short cycles is 3 - colorable
Two cycles are adjacent if they have an edge in common. Suppose that G is a planar graph, for any two adjacent cycles C1 and C2, we have |C1| + |C2| ≥ 11, in particular, when |C1| = 5, |C2| ≥ 7. We show that the graph G is 3-colorable.
متن کاملEvery Monotone 3-Graph Property is Testable
Let k ≥ 2 be a fixed integer and P be a property of k-uniform hypergraphs. In other words, P is a (typically infinite) family of k-uniform hypergraphs and we say a given hypergraph H satisfies P if H ∈ P . For a given constant η > 0 a k-uniform hypergraph H on n vertices is η-far from P if no hypergraph obtained from H by changing (adding or deleting) at most ηn edges in H satisfies P . More pr...
متن کاملEvery Graph is a Self - Similar Set
In this paper we prove that every graph (in particular S1) is a selfsimilar space and that [0, 1] is a self-similar set that is not the product of topological spaces, answering two questions posed by C. Ruiz and S. Sabogal in [6].
