We determine the Taylor spectra of quotient tuples of the -shift on Drury-Arveson spaces with finite-dimensional coefficient spaces. We show the the Taylor spectrum can be descr…

On Schatten-class perturbations of Toeplitz operators
Michael Didas, Jörg Eschmeier, Dominik Schillo
We characterize the commutant of the analytic Toeplitz operators modulo operators of Schatten-p-class on suitable multivariable domains. We show that a result of J. Xia on compact…
