New families of graceful graphs.
Ars Comb., 2003The gracefulness of graphs obtained by the join and union operations is studied. Particularly, the classes \(G\, \cup \, H\) (\(G\) is \(\alpha \)-labeled, \(H\) is pseudograceful), \(G+\overline K_n\) (\(G\) is a Skolem-graceful graph), \(\overline K_n+mK_2\) and \(C_m\cup S_n\) (\(S_n\) is a star on \(n+1\) vertices) are discussed.

Graceful graphs with pendant edges
Australas. J Comb., 2005The author gives graceful labelings for the graphs \(G+ nK\), and \(G\odot nK\), where \(G\) is a graceful graph whose order is greater than its size. He also provides a graceful labeling for the unicyclic graph formed when an arbitrary number of pendant edges are attached to a cycle.

On graceful and cordial labeling of shell graphs.
Ars Comb., 2011A graceful labeling, an \(\alpha \)-labeling (called here \(\Delta \)-labeling), and a cordial labeling of yet another special class of graphs are provided. Unfortunately, the paper contains many typographical, grammatical and stylistic errors.

Two classes of graceful graphs
Ars Comb., 2000A graph is graceful if it allows a labelling \(\varphi \) of its vertices by distinct nonnegative integers such that, for edges \(uv\), \(|\varphi (u)-\varphi (v)|\) attains all values from \(\{1,2,\dots ,q\}\), where \(q\) is the number of edges. This paper identifies two new classes of graceful graphs.
