摘要：

A geometrical representation of the set of four complex numbers which are the spectrum of 4-dimensional entrywise nonnegative real matrices is provided. The characterization is based on the result for the nonnegative inverse eigenvalue problem (NIEP) from the coefficients of the characteristic polynomial given in [16]. (C) 2013 Elsevier Inc.
