,A Generalization of the tan 2Θ Theorem,.),where A. and A. are restrictions of A onto the subspaces . and ., respectively, we study the variation of the invariant subspace 5jo under bounded self-adjoint perturbations V that are off-diagonal with respect to the decomposition .. We obtain sharp two-sided estimates on the norm of the differe

Uniform Approximation by Solutions of Elliptic Equations and Seminormality in Higher Dimensions,nd main result is a generalization of Putnam’s inequality to higher dimensions that deals with Riesz transforms models of seminormal self-adjoint systems of Hilbert space operators. Both results share a common origin illustrated in the similar way they are derived from uniform estimates of integral

On Super-wavelets,f super-wavelet was first introduced by Han and Larson. It is known that there exist super-wavelets with very interesting properties and some of these super-wavelets may have important applications. On the other hand, many questions concerning general properties of super-wavelets remain open. In this paper, we will answer some of these questions.

Conference proceedings 2004icles. Particular emphasis lies on highlighting the interplay between operator theory and applications from other areas, such as multi-dimensional systems and function theory of several complex variables, distributed parameter systems and control theory, mathematical physics, wavelets, and numerical analysis..
