In this paper it is proved that the exponential generating function of the numbers, denoted by N(p, q), of irreducible coverings by edges of the vertices of complete bipartite graphs Kp.q equals exp(xe r + ye x -x -y -xy) -t.

Jakubik has shown that for discrete modular lattices all graph isomorphisms are given by certain direct product decompositions. Duffus and Rival have proved a similar theorem for graded lattices which are atomistic and coatomistic. Modifying some of the results of Duffus and Rival we give a common g
## Abstract We give a 4βchromatic planar graph, which admits a vertex partition into three parts such that the union of every two of them induces a forest. This solves a problem posed by BΓΆhme. Also, by constructing an infinite sequence of graphs, we show that the cover degeneracy can be arbitraril
A method is described for calculating the mean cover time for a particle performing a simple random walk on the vertices of a finite connected graph. The method also yields the variance and generating function of the cover time. A computer program is available which utilises the approach to provide
Let G be a line graph. Orlin determined the clique covering and clique partition numbers cc(G) and cp(G). We obtain a constructive proof of Orlin's result and in doing so we are able to completely enumerate the number of distinct minimal clique covers and partitions of G, in terms of easily calculab
