摘要：

A previous paper by D. Hershkowitz [Linear and Multilinear Algebra 14 (1983) 315-342] described the possible eigenvalues of an n x n matrix when 2n - 3 entries are fixed and the others vary, This paper describes the possible eigenvalues of a pk x pk matrix, partitioned into k x k blocks of size p x p when 2k - 3 blocks are fixed and the others vary.
