摘要：
Let sigma = (lambda(1), lambda(2), lambda(3), lambda(4), lambda(5),) be a list of complex numbers with lambda(1) + lambda(2) + lambda(3) + lambda(4) + lambda(5) = 0. Necessary and sufficient conditions for the existence of an entry-wise nonnegative 5 x 5 matrix A with spectrum sigma are presented. (C) 1999 Elsevier Science Inc. All rights reserved.
