that path joining two copies of m-pan graph are signed product cordial, when (m= 3, 4). Further we show that the path union of r-copies of 3-pan graph are signed product cordial for r≡ 0, 1, 2, 3 (mod 4).
Abstract
In this paper we investigate signed product cordial labeling of some pan graphs. We proved that path joining two copies of m-pan graph are signed product cordial, when (m = 3, 4). Further we show that the path union of r-copies of 3-pan graph are signed product cordial for r ≡ 0, 1, 2, 3(mod 4).
