Abstract
Extending some properties from the Euclidean plane to any normed plane, we show the validity of the Monma–Paterson–Suri–Yao algorithm for finding the maximum-weighted spanning tree of a set of n points, where the weight of an edge is the distance between the end points measured by the norm and there are not repeated distances. For strictly convex normed planes, we expose a strategy for moving slightly the points of the set in order to obtain distinct distances.
