For a graph G and an integer
an independent set of vertices in G}. Enomoto proved the following theorem. Let s โฅ 1 and let G be a (s + 2)-connected graph. Then G has a cycle of length โฅ min{|V (G)|, ฯ 2 (G) -s} passing through any path of length s. We generalize this result as follows. Let k โฅ 3 and s โฅ 1 and let G be a (k+s-1)-connected graph. Then G has a cycle of length โฅ min{|V (G)|, 2 k ฯ k (G) -s} passing through any path of length s.

We propose a conjecture: for each integer k โฅ 2, there exists N (k) such that if G is a graph of order n โฅ N (k) and d(x) + d(y) โฅ n + 2k -2 for each pair of nonadjacent vertices x and y of G, then for any k independent edges e 1 , . . . , e k of G, there exist If this conjecture is true, the condi

A graph G is said to be P t -free if it does not contain an induced path on t vertices. The i-center C i (G) of a connected graph G is the set of vertices whose distance from any vertex in G is at most i. Denote by I(t) the set of natural numbers i, t/2 โค i โค t -2, with the property that, in every c
