If H is an r-uniform hypergraph of order p without (r + 1)-cliques, then the transversal number of H has an upper bound in terms of the parameter c = p -2r. As corollaries of the main theorem, lower bounds for the largest order of r-uniform hypergraphs with specified transversal number and for the s

Let G be a simple graph of order n and minimum degree $. The independent domination number i(G) is defined to be the minimum cardinality among all maximal independent sets of vertices of G. In this paper, we show that i(G) n+2$&2 -n$. Thus a conjecture of Favaron is settled in the affirmative.

## Abstract The path number of a graph __G__, denoted __p(G)__, is the minimum number of edge‐disjoint paths covering the edges of __G.__ LovΓ‘sz has proved that if __G__ has __u__ odd vertices and __g__ even vertices, then __p(G)__ ≀ 1/2 __u__ + __g__ ‐ 1 ≀ __n__ ‐ 1, where __n__ is the total numbe

The Ramsey number r(H, G) is defined as the minimum N such that for any coloring of the edges of the N-vertex complete graph KN in red and blue, it must contain either a ted H or a blue G. In this paper we show that for any graph G without isolated vertices, r(K,, G)< 2qf 1 where G has q edges. In o
