Applications of the $\otimes_h$-product of labeled (di)graphs: Langford sequences and decompositions
Susana-Clara López, Francesc-Antoni Muntaner-Batle · arXiv (Cornell University) · 2014
The $\otimes_h$-product is a generalization of the direct product of digraphs. The use of super edge-magic (SEM) digraphs points out many relations among different types of labelings, specially when SEM digraphs appear as a factor of the $\otimes_h$product. In this paper, we show two applications that have their origin in this last direction. The first one is related to Skolem and Langford sequences and the second one to decompositions of bipartite graphs.
