Denote by e\*(L) and ~,(L) respectively the upper length and lower length of a finite lattice L. The lattice L is said to be uniform if for each integer k with e,(L) < k < Β’\*(L) there exists in L a maximal chain of length k. It is shown that the closed-set lattice of a finite graph G is uniform if
In this paper we give an alternative proof of the constant inertia theorem for convex compact sets of complex matrices. It is shown that the companion matrix whose non-trivial column is negative satisfies the directional Lyapunov condition (inclusion) for real multiplier vectors. An example of a rea
