Sažetak

A (p, q) -graph G is said to be (1, N ) -Arithmetic if there is a function φ from the vertex set V (G) to {0, 1, N, (N + 1), 2N, (2N + 1), . . . , N (q − 1), N (q − 1) + 1} so that the values obtained as the sums of the labelling assigned to their end vertices, can be arranged in the arithmetic progression {1, N + 1,
2N + 1, . . . , N (q − 1) + 1} . In this paper we prove that the arbitrary supersubdivision of disconnected paths Pn U Pr and disconnected path and cycle Pn U Pr are (1, N ) -Arithmetic Labelling for all positive integers N > 1 .
