## Abstract The following theorem is proved: Let __G__ be a graph with __p__ β₯ 3 points such that for some __n__, 3 β€ __n__ β€ __p__, any __n__ points lie on a unique smallest connected subgraph. Then __G__ = __C__~__n__~+1 or __G__ is a tree, and conversely.
A total dominating function (TDF) of a graph G = (V, E) is a function f: V~ [0, 1] such that for each v~ V, ~u~Ntv)f(u)>~ 1, where N(v) denotes the set of neighbours of v. Although convex combinations of TDFs are also TDFs, convex combinations of minimal TDFs (MTDFs) are not necessarily minimal. An
