Natural representations of the multiplicity of an analytic operator-valued function at an isolated point of the spectrum
Representations are given for the multiplicity of an analytic operator-valued function A at an isolated point z 0 of the spectrum in the form of kernels and ranges of Hankel and Toeplitz matrices whose entries are derived from the Taylor coefficients of A and the Laurent coefficients of A -1 about z...
