| Research Abstract |
(1) We show that there are two completely independent spanning trees in the Cartesian product of 2-connected graphs. Also, we determine the(h, k)-domination number of an iterated line digraph.
(2) We improve upper and lower bounds on the minimum size of a fault-tolerant gossip graph.
(3) We design a linear time algorithm for computing the L(2, 1)-labeling number of a tree. Besides, we present tight upper and lower bounds on the(p, q)-total labeling number of a tree and a tight upper bound on the(2, 1)-total labeling number of an outerplanar graph.
(4) We design a linear time algorithm for computing the queue-number of a maximal outerplanar graph.
