Center node: "packing plane spanning trees and paths in complete geometric graphs"
  Abstract: We consider the following question: How many edge-disjoint plane spanning trees are contained in a complete geometric graph GKn on any set S of n points in general position in the plane? We show that this number is in Ω(n). Further, we consider variants of this problem by bounding the diameter and the degree of the trees (in particular considering spanning paths).
