Title: Maximal Spanning Trees For Certain Plannar Graphs
Authors: Azaria Paz
Abstract: It is shown that a plannar connected map with no 'islands' or 'island groups', with n-finite countries and such that every finite country has at least 3 bordering edges, can be spanned by a tree with number of leaves less or equal than lower-bound(sqrt(n/2)) This bound is shown to be sharp.
