The NIEP has a long history andis a known hard (perhaps the hardest in matrix analysis?) and sought afterproblem. Thus, there are many subproblems and relevant results in a varietyof directions. We survey most work on the problem and its several variants,with an emphasis on recent results, and include 130 references. The surveyis divided into: a) the single eigenvalue problems; b) necessary conditions; c)low-dimensional results; d) sufficient conditions; e) appending 0’s to achieverealizability; f) the graph NIEP’s; g) Perron similarities; and h) the relevanceof Jordan structure.
