Abstract
Two plane drawings of geometric graphs on the same set of points are called disjoint compatible if their union is plane and they do not have an edge in common. For a given set S of 2n points two
plane drawings of perfect matchings M1 and M2 (which do not need to be disjoint nor compatible) are disjoint treecompatible if there exists a plane drawing of a spanning tree T on S which is
disjoint compatible to both M1 and M2.
We show that the graph of all disjoint treecompatible perfect geometric matchings on 2n points in convex position is connected if and only if 2n ≥ 10. Moreover, in that case the diameter
of this graph is either 4 or 5, independent of n.
