Sequential Multidimensional Spectral Estimation
By considering an empirical approximation, and a new class of operators that we will call walking operators, we construct, for any positive ND-toeplitz matrix, an... -

Unitary equivalence to truncated Toeplitz operators
In this paper we investigate operators unitarily equivalent to truncated Toeplitz operators. We show that this class contains certain sums of tensor products of... -
