It is shown that, if t is an integer !3 and not equal to 7 or 8, then there is a unique maximal graph having the path P t as a star complement for the eigenvalue Γ2: The maximal graph is the line graph of K m,m if t ΒΌ 2mΓ1, and of K m,m ΓΎ1 if t ΒΌ 2m. This result yields a characterization of L(G ) wh

Abstract
A path on n vertices is denoted by P~n~. For any graph H, the number of isolated vertices of H is denoted by i(H). Let G be a graph. A spanning subgraph F of G is called a {P~3~, P~4~, P~5~}βfactor of G if every component of F is one of P~3~, P~4~, and P~5~. In this paper, we prove that a bipartite graph G has a {P~3~, P~4~, P~5~}βfactor if and only if i(G β S β M) β¦ 2|S| + |M| for all S β V(G) and independent M β E(G).

In this article, we consider the following problem: Given a bipartite graph G and a positive integer k, when does G have a 2-factor with exactly k components? We will prove that if , then, for any bipartite graph H = (U 1 , U 2 ; F ) with |U 1 | β€ n, |U 2 | β€ n and β(H) β€ 2, G contains a subgraph i
In this paper we obtain two sufficient conditions, Ore type (Theorem 1) and Dirac type (Theorem 2). on the degrees of a bipartite oriented graph for ensuring the existence of long paths and cycles. These conditions are shown to be the best possible in a sense. An oriented graph is a digraph without
We show that any k-regular bipartite graph with 2n vertices has at least \ (k&1) k&1 k k&2 + n perfect matchings (1-factors). Equivalently, this is a lower bound on the permanent of any nonnegative integer n\_n matrix with each row and column sum equal to k. For any k, the base (k&1) k&1 Γk k&2 is l
## Abstract We consider various edge disjoint partitions of complete bipartite graphs. One case is where we decompose the edge set into edge disjoint paths of increasing lengths. A graph __G__ is __pathβperfect__ if there is a positive integer __n__ such that the edge set __E__(__G__) of the graph
