摘要

我们对林格尔(Ringel)于 1967 年提出的著名的奥伯沃尔法赫(Oberwolfach)问题进行了归纳。我们假设有一对情侣(此处为偶数整数),并假设他们必须连续几晚坐在圆桌上,使每个人与他的伴侣恰好相邻一次,与其他每个人恰好相邻一次。我们称这个问题为恩爱夫妻的奥伯沃尔法赫问题。当 、 时,该问题与所谓的避开配偶变式不谋而合,后者是由黄、科齐格和罗莎于 1979 年提出的。而当 或 等于夜数时,则对应于爱配偶变式或蜜月变式,这两个变式最近分别由 Bolohan 等人和 Lepine 与 Sajna 进行了研究。在本文中,对于每一种可能的选择,我们都构建了许多种夫妻恩爱的奥伯沃尔法赫问题的解。我们还获得了蜜月变量的新解。

The Oberwolfach problem with loving couples

We generalize the well-known Oberwolfach problem posed by Ringel in 1967. We suppose to have v 2 $\frac{v}{2}$ couples (here v 4 $v\ge 4$ is an even integer) and suppose that they have to be seated for several nights at t $t$ round tables in such a way that each person seats next to his partner exactly r 0 $r\ge 0$ times and next to every other person exactly once. We call this problem the Oberwolfach problem with loving couples. When r = 0 $r=0$ , the problem coincides with the so-called spouse-avoiding variant, which was introduced by Huang, Kotzig, and Rosa in 1979. While if either r = 2 $r=2$ or r $r$ equals the number of nights, it corresponds to the spouse-loving variant or to the Honeymoon variant, which was recently studied by Bolohan et al. and by Lepine and Sajna, respectively. In this paper, for each possible choice of r $r$ , we construct many classes of solutions to the Oberwolfach problem with loving couples. We also obtain new solutions to the Honeymoon variant.

期刊介绍: The Journal of Combinatorial Designs is an international journal devoted to the timely publication of the most influential papers in the area of combinatorial design theory. All topics in design theory, and in which design theory has important applications, are covered, including: block designs, t-designs, pairwise balanced designs and group divisible designs Latin squares, quasigroups, and related algebras computational methods in design theory construction methods applications in computer science, experimental design theory, and coding theory graph decompositions, factorizations, and design-theoretic techniques in graph theory and extremal combinatorics finite geometry and its relation with design theory. algebraic aspects of design theory. Researchers and scientists can depend on the Journal of Combinatorial Designs for the most recent developments in this rapidly growing field, and to provide a forum for both theoretical research and applications. All papers appearing in the Journal of Combinatorial Designs are carefully peer refereed.
