摘要：
We prove that the exponent set of symmetric primitive (0, 1) matrices with zero trace (the adjacency matrices of the simple graphs) is {2,3,...,2n-4}{minus 45 degree rule}S, where S is the set of all odd numbers in {n-2,n-1,...,2n-5}. We also obtain a characterization of the symmetric primitive matrices with zero trace whose exponents attain the upper bound 2n-4. © 1990.
