几类奇偶符号图的刻画

Characterizations of Some Parity Signed Graphs

Mukti Acharya, Joseph Varghese Kureethara, Thomas Zaslavsky

摘要:

我们描述奇偶标记的签署图,等价地,削减的基本图形,有几乎相等的边。我们刻画了平衡符号图是奇偶符号图。给出了所有宇称符号星、双星、圈、路和完全二部图的结构刻画。图的rna数是具有几乎相等边的最小割尺寸,我们在几类奇偶符号图中发现了它。

英文摘要:

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.
