Abstract

The origami graph, On, n≥3, is a graph formed by a central cycle with origami folds, where each fold consists of two C3 cycles. The barbell origami graph, BOn for n≥3 is obtained by copying a On and connecting two graphs with a bridge. In this research, we determined the partition dimension of the origami graphs and its barbell.

Abstract

We propose sum rules for permutations pn(k) of the ensemble {1,2,...,n} with k fixed points, in the form of partial sums of their moments. The corresponding identities involve Stirling numbers of the first kind s(q,r). Using a formula due to Vassilev-Missana and the Schlomlich expression of Stirling numbers, we also deduce sum rules for binomial coefficients. Connections with Bell numbers Bn are outlined.

Abstract

Let f : V(G) \to [1,|V(G)|] be a bijective mapping of the vertex set of a graph G to the integers 1 through |V(G)|. A labeling f is defined as a local edge antimagic labeling if, for any two adjacent edges uv and vx in E(G), their weights satisfy wf(uv) ≠ wf(vx), where the weight of an edge uv is given by wf(uv) = f(u) + f(v). The weight wf induces a proper edge coloring on G. The local edge antimagic chromatic number of G, denoted χlea'(G), is the minimum number of colors required among all colorings induced by local edge antimagic labelings of G. In this paper, we investigate the local edge antimagic coloring of join product of graphs, particularly for independent sets, paths, and cycles.
