L(j, k)-labeling number of Cartesian product of path and cycle

For positive numbers and , an -labeling of is an assignment of numbers to vertices of such that if , and if . The span of is the difference between the maximum and the minimum numbers assigned by . The -labeling number of , denoted by , is the minimum span over all -labelings of . In this article, we completely determine the -labeling number () of the Cartesian product of path and cycle.
