Block Toeplitz operators with rational symbols and discrete singular systems
Konegerie, Abraham (University of the Western Cape, 2001)This thesis concerns block Toeplitz operators (equations). Consider the block Toeplitz operator T = [<I> k-j ]k,j=O' where the <I>k are complex m x m matrices such that 00 (0.1) v=-oo The norm in (0.1) is the usual ... -
Left versus right canonical wiener-hopf factorization for rational matrix functions: an alternative version
Petersen, Mark Adam (University of the Western Cape, 1995)It is an established fact that both canonical and non-canonical Wiener-hopf factorizations of matrix functions play an important role in various aspects of mathematical analysis and its applications. Indeed, for instance, ...
