**An attempt to classify bipartite graphs by chromatic**

Let Γ denote a bipartite Q-polynomial distance-regular graph with diameter D⩾4. We show that Γ is the quotient of an antipodal distance-regular graph if and only if one of the following holds.... The maximum biclique problem is polynomial for bipartite graphs [3], and NP-hard for general graphs [25]. The maximum edge biclique problem was shown to be NP-hard by Peeters [20]. Approximation algorithms for node and edge deletion biclique problems are given by Hochbaum [12]. Enumerating maximal bicliques has attracted a lot of attention in the last decade. The algorithms in [17,18

Let Γ denote a bipartite Q-polynomial distance-regular graph with diameter D⩾4. We show that Γ is the quotient of an antipodal distance-regular graph if and only if one of the following holds.... Bicliques are complements of bipartite graphs; as such each consists of two cliques joined by a number of edges. In this paper we study algebraic aspects of the chromatic polynomials of these graphs.

Spectra of graphs – Monograph – February 1, 2011 which the on-line version still is calledipm.pdf. We aim at researchers, teach-ers, and graduate students interested in graph spectra. The reader is assumed to be familiar with basic linear algebra and eigenvalues, but we did include a chapter on some more advanced topics in linear algebra, like the Perron-Frobenius theorem and

- Let G be a graph and A(G) the adjacency matrix of G. The polynomial π(G,x)=per(xI−A(G)) is called the permanental polynomial of G, and the permanental sum of G is the summation of the absolute
- For a simple bipartite graph and an integer t ‚ 2, we consider the problem of ﬁnding a minimum-weight t -factor under the restric- tion that it contains no complete bipartite graph K t,t as a subgraph.
