An upper bound on the P3-Radon number
The generalization of classical results about convex sets in Rn to abstract convexity spaces, defined by sets of paths in graphs, leads to many challenging structural and algorithmic problems. Here we study the Radon number for the P3-convexity on graphs. A set R of vertices of a graph G is P3-convex if no vertex in V (G) \ R has two neighbours in R. The P3-convex hull of a set of vertices is t...
متن کاملOn trees attaining an upper bound on the total domination number
A total dominating set of a graph $G$ is a set $D$ of vertices of $G$ such that every vertex of $G$ has a neighbor in $D$. The total domination number of a graph $G$, denoted by $gamma_t(G)$, is~the minimum cardinality of a total dominating set of $G$.

متن کاملAn Upper Bound on the First Zagreb Index in Trees
In this paper we give sharp upper bounds on the Zagreb indices and characterize all trees achieving equality in these bounds. Also, we give lower bound on first Zagreb coindex of trees.
متن کاملAn Upper Bound on the Reduction Number of an Ideal
Let A be a commutative ring and I an ideal of A with a reduction Q. In this paper we give an upper bound on the reduction number of I with respect to Q, when a suitable family of ideals in A is given. As a corollary it follows that if some ideal J containing I satisfies J = QJ , then I = QI, where v denotes the number of generators of J/I as an A-module.
متن کاملAn upper bound on the number of Steiner triple systems
Richard Wilson conjectured in 1974 the following asymptotic formula for the number of n-vertex Steiner triple systems: STS(n) = ( (1 + o(1)) n e2 )n2 6 . Our main result is that STS(n) ≤ ( (1 + o(1)) n e2 )n2 6 . The proof is based on the entropy method. As a prelude to this proof we consider the number F (n) of 1factorizations of the complete graph on n vertices. Using the KahnLovász theorem i...
