In this paper we shall discuss the following set of n + 1 linear inequalities:
If we let , and Z = (zi) (i = 0, 1,…, n) be (n+1)-dimensional column vectors, and define the n+1 by n+1 tridiagonal matrix Dn(ϕ) by
the set of inequalities (1) may be written
where An= Dn(1) and zi≥ 0 (i = 0, 1,…, n). In sections 2 and 3, we
