5 Jun 2020 | Abstract: | We describe parity labelings of signed graphs; equivalently, cuts of the
underlying graph that have nearly equal sides. We characterize the balanced
signed graphs which are parity signed graphs. We give structural
characterizations of all parity signed stars, bistars, cycles, paths and
complete bipartite graphs. The rna number of a graph is the smallest cut size
that has nearly equal sides; we find it for a few classes of parity signed
graphs. | Source: | arXiv, 2006.3584 | Services: | Forum | Review | PDF | Favorites |
