2010
Computers and Mathematics with Applications
In this paper, the conjecture about the kth lower multiexponent f (n, k) proposed by R.A. Brualdi and B. Liu is proved to be true for the following cases: (1) k = n − i, where i = 2, 3, 4, 5; (2) small n, where n ≤ 8; (3) the class of primitive micro-symmetric digraphs of order n.
