Abstract: : A graph H in which a vertex is distinguished from other vertices is called a rooted graph and the vertex is called the root of H. Let H be a rooted graph. The graph H(n) obtained by identifying the roots of n copies of H is called the one-point union of n copies of the graph H. A function from vertex set of a graph to the set {0,1}, which assigns the label |f(u)-f(v)| or each edge uv, is called a cordial labelling of the graph if the number of vertices labelled 0 and number of vertices labelled 1 differ by at most 1, and similar condition is satisfied by the edges of the graph. In this paper we discuss cordial labelling of one point union of grid graph, cycle with one chord and cycle with twin chords.
Keywords: Cordial graph, One Point Union
