On Heterochromatic Out-directed Spanning Trees in Tournaments
نویسندگان
چکیده
Given a tournament T , let h(T ) be the smallest integer k such that every arc-coloring of T with k or more colors produces at least one out-directed spanning tree of T with no pair of arcs with the same color. In this paper we give the exact value of h(T ).

Spanning k-arc-strong subdigraphs with few arcs in k-arc-strong tournaments
Given a k-arc-strong tournament T , we estimate the minimum number of arcs possible in a k-arc-strong spanning subdigraph of T . We give a construction which shows that for each k ≥ 2 there are tournaments T on n vertices such that every k-arc-strong spanning subdigraph of T contains at least nk+ k(k−1) 2 arcs. In fact, the tournaments in our construction have the property that every spanning s...
متن کاملCounting the number of spanning trees of graphs
A spanning tree of graph G is a spanning subgraph of G that is a tree. In this paper, we focus our attention on (n,m) graphs, where m = n, n + 1, n + 2, n+3 and n + 4. We also determine some coefficients of the Laplacian characteristic polynomial of fullerene graphs.

Let $G=(V,E)$, $V={1,2,ldots,n}$, $E={e_1,e_2,ldots,e_m}$,be a simple connected graph, with sequence of vertex degrees$Delta =d_1geq d_2geqcdotsgeq d_n=delta >0$ and Laplacian eigenvalues$mu_1geq mu_2geqcdotsgeqmu_{n-1}>mu_n=0$. Denote by $Kf(G)=nsum_{i=1}^{n-1}frac{1}{mu_i}$ and $t=t(G)=frac 1n prod_{i=1}^{n-1} mu_i$ the Kirchhoff index and number of spanning tree...
متن کاملAbsorbent sets and kernels by monochromatic directed paths in m-colored tournaments
In this paper, we consider the following problem due to Erdős: for each m ∈ N, is there a (least) positive integer f(m) so that every finite mcolored tournament contains an absorbent set S by monochromatic directed paths of f(m) vertices? In particular, is f(3) = 3? We prove several bounds for absorbent sets of m-colored tournaments under certain conditions on the number of colors of the arcs i...
متن کاملStar-factors of tournaments
Let Sm denote the m-vertex simple digraph formed by m− 1 edges with a common tail. Let f(m) denote the minimum n such that every n-vertex tournament has a spanning subgraph consisting of n/m disjoint copies of Sm. We prove that m lgm−m lg lgm ≤ f(m) ≤ 4m − 6m for sufficiently large m. If D is an acyclic digraph of order n, then D occurs as a subgraph of every tournament with at least 2 vertices...
