TITLE: How to find Suleimanova's work on the Nonnegative Inverse Eigenvalue Problem?
QUESTION [12 upvotes]: Many papers cite the work of Suleimanova when studying inverse eigenvalue problems - in particular, the nonnegative inverse eigenvalue problem (NIEP).  However, I cannot seem to find her work anywhere.  She proves an important result for lists of real eigenvalues. There is apparently one paper in Russian... somewhere.
Does anyone know where I can find her work?
How can people cite her work, if there's only one known paper that's in Russian?
Thanks.

REPLY [5 votes]: A multi-set of real numbers $\Lambda = \{\lambda_1,\dots,\lambda_n\}$ is called a Suleĭmanova spectrum if $\Lambda$ contains one positive element and $\sum_{i=1}^n \lambda_i \geq 0$. 
Suleĭmanova [Doklady Akad. Nauk SSSR (N.S.) 66, 343–345 (1949); MR0030496] loosely proved that every such set is realizable, i.e., that it is the spectrum of an $n$-by-$n$ nonnegative matrix. 
Appendix B of Joanne Swift's 1972 master's thesis Location of the Characteristic Roots of Stochastic Matrices at McGill University contains an English translation of Suleĭmanova's seminal paper.
Friedland [Israel J. Math. 29, no. 1, 43–60 (1978); MR0492634] and Perfect [Duke Math. J. 20, 395–404 (1953); MR0055969] proved Suleĭmanova's result via companion matrices. However, constructing the companion matrix of a Suleĭmanova spectrum is computationally prohibitive. Recently, I gave a constructive proof of Suleĭmanova's result [Electron. J. Linear Algebra 31, 306–312 (2016); MR3504411] using permutative matrices.
