When a forest, narrowed to an atom of subset algebra, turns out to be a tree

Combinatorics 2025-02-18 v3

Abstract

It is proved that the restriction of a kk and (k1)(k-1)-component directed spanning forest of minimal weight to an atom of the subset algebra generated by the sets of vertices of trees of kk-component minimal spanning forests is a tree. For spanning minimal forests consisting of fewer components, this property, generally speaking, does not exist.
