✦ Synopsis


In answer to the open questions proposed by Henning and Slater, we give sharp upper bounds on the upper signed domination number of a regular graph and on the signed domination number of a connected cubic graph. Let G = (V, E) be a simple graph. For v E V, we denote by d(u) the degree of v in V, by N(v) the neighborhood of v, and by N[v]=N(u)U{v} its closed neighborhood.

Suppose G is a graph on n vertices with minimum degree r. Using standard random methods it is shown that there exists a two-coloring of the vertices of G with colors, +1 and &1, such that all closed neighborhoods contain more 1's than &1's, and all together the number of 1's does not exceed the numb

Let G be a simple graph of order n. The independent domination number i(G) is defined to be the minimum cardinality among all maximal independent sets of vertices of G. Motivated by work of Cockayne et al. (1991) and Cockayne and Mynhardt (1989), we investigate the maximum value of the product of th

The key to Seymour's Regular Matroid Decomposition Theorem is his result that each 3-connected regular matroid with no R 10or R 12 -minor is graphic or cographic. We present a proof of this in terms of signed graphs.
