and Richard S. Varga Received September 11, 1967 1. Introduction If a given irreducible n
xn complex matrix A admits s, i^s^n, Gerschgorin disks which are isolated from the remaining
disks, then it is well known that the union of these s disks contains s eigenvalues oí A. It has
been shown in [5], [9] and [11] that, for the case where s = 1, algorithms exist which yield the …
