Magical coronations of graphs
نویسندگان
چکیده
A (p, q) graph G is called edge-magic if there exists a bijective function f : V (G) ∪ E(G) → {1, 2, . . . , p + q} such that f(u) + f(v) + f(uv) is constant for any edge uv of G. Moreover, G is said to be super edgemagic if f(V (G)) = {1, 2, . . . , p}. Every super edge-magic (p, q) graph is harmonious, sequential and felicitous whenever it is a tree or satisfies q ≥ p. In this paper, we prove that the n-crown, a cycle with n pendant edges attached at each vertex, is super edge-magic for any positive integer n, and thus extend what was known about the harmoniousness, sequentialness and felicitousness of such graphs. We also present three results on attaching pendant edges to the vertices of certain super edge-magic graphs to obtain more super edge-magic graphs. ∗ Dedicated to Tadashi Iida Australasian Journal of Combinatorics 26(2002), pp.199–208

In this paper, a complete characterization of the (super) edge-magic linear forests with two components is provided. In the process of establishing this characterization, the super edge-magic, harmonious, sequential and felicitous properties of certain 2-regular graphs are investigated , and several results on super edge-magic and felicitous labelings of unions of cycles and paths are presented...
