Abstract: The distance d(u, v) from a vertex u of graph G to a vertex v is the length of a shortest u to v path. The eccentric sequences were the first distance related sequences introduced for undirected graphs. The eccentricity e(v) of v is the distance of a farthest vertex from v. The eccentric sequence of a graph G is a list of the eccentricities of vertices of graph G arranged in non-decreasing order. In this paper we determine the eccentric sequence of join of an empty graph and path graph(ie fan graph) and the eccentric sequence of the Cartesian product of paths P2 and Pn (ie Ladder graph).
Keywords: Cartesian Product of Graphs, Degree Sequence of Graphs, Eccentric Sequence of Graphs, Join of A Graph.
