Let G = (V (G), E(G)) be any finite, undirected, simple graph. The maximun size of a clique containing a vertex \(\mathit{x}\) \(\in\) V (G) is called the clique centrality of \(\mathit{x}\) , denoted by \(\omega\)G (\(\mathit{x}\)) . A set D \(\subseteq\) V (G) is said to be a p...

In this paper, a modified Adomian decomposition method (MADM) for solving the hyperbolic telegraph equation is proposed. The MADM introduces a new inverse partial differential operator that can speed up the convergence rate of the standard ADM. We also present a technique for con...

For a connected nontrivial graph G, the maximum linear forest of G is the linear forest having maximum number of edges. The number of edges in a maximum linear forest is denoted by \(\ell\)`(G). In this paper we determine the maximum linear forest of the join and union of nontri...
