Graceful Signed Graphs on C k 3
نویسنده
چکیده
In [4], we have proved the necessary condition for sigraphs on union of k copies cycles of length three with one vertex in common denoted by C 3 to be graceful and sufficiency part of the theorem was discussed in certain special cases when all rim edges are negative and form a maximum matching. In this paper, we discuss the sufficiency part of the theorem on gracefulness of sigraphs on C 3 partially, in particularly, some of the rim edges are positive and others are negative.

Graceful labelings of the generalized Petersen graphs
A graceful labeling of a graph $G=(V,E)$ with $m$ edges is aninjection $f: V(G) rightarrow {0,1,ldots,m}$ such that the resulting edge labelsobtained by $|f(u)-f(v)|$ on every edge $uv$ are pairwise distinct. For natural numbers $n$ and $k$, where $n > 2k$, a generalized Petersengraph $P(n, k)$ is the graph whose vertex set is ${u_1, u_2, cdots, u_n} cup {v_1, v_2, cdots, v_n}$ and its edge set...
