✦ Synopsis


We show new lower and upper bounds on the maximum number of maximal induced bipartite subgraphs of graphs with n vertices. We present an infinite family of graphs having 105 n=10 % 1:5926 n ; such subgraphs show an upper bound of O(12 n=4 ) ¼ O(1:8613 n ) and give an algorithm that finds all maximal induced bipartite subgraphs in time within a polynomial factor of this bound. This algorithm is used in the construction of algorithms for checking k-colorability of a graph.

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 | ≤ n, |U 2 | ≤ n and ∆(H) ≤ 2, G contains a subgraph i
