Any nonvoid lattice of subspaces from R" is known to be a complete lattice, and hence it has a largest and smallest element. Here we show that for a specific class of subspaces also the converse is true. If this class has a largest and a smallest element, then it is a complete lattice. Within the co

Given a (finite or infinite) set X, a collection C P(X ) of subsets of X is called a hierarchy if it satisfies the condition ` '' In this note, we characterize maximal hierarchies as set systems that contain the empty set, the full set, and all one-element sets, and in addition satisfy either one of
