A note on maximal plane subgraphs of the complete twisted graph containing perfect matchings

Elsa OmaÃ±a-Pulido, Eduardo Rivera-Campo

The twisted graph $T_{n}$ is a drawing of the complete graph with $n$ vertices $v_{1}, v_{2}, \dots, v_{n}$ in which two edges $v_{i} v_{j}$ ( $i < j$ ) and $v_{s} v_{t}$ ( $s < t$ ) cross if…

Partitions of complete twisted graphs into plane spanning trees

Ana Paulina Figueroa, Eduardo Rivera-Campo

We characterize all partitions of the complete twisted graph $T_{2 n}$ into plane spanning trees. In the case of partitions of $T_{2 n}$ into isomorphic plane spanning trees, we show…
