Abstract
In the paper, asymptotics for eigenvalues of Hermitian, compact
operators, generated by infinite, banded matrices is obtained in
terms of the asymptotics of their matrix entries. Analogues for
banded matrices of Gershgorin's disks theory are discussed.
Key words: Banded matrices, eigenvalues, Gershgorin’s disks, spectral projection.
