On image-labeling of Cartesian product of a cycle and a path Original Research Article

A image-labeling of a graph image is a function image from the vertex set image to image such that image if image and image if image. The image-labeling problem is to find the image-labeling number image of a graph image, which is the minimum cardinality image such that image has a image-labeling. In this paper, we determine the image-labeling number of the Cartesian product of a cycle and a path.
