Research in robust control theory has been one of the most active areas of mainstream
systems theory since the late 70s. This research activity has been at the confluence of …

The theory of operator spaces is very recent and can be described as a non-commutative
Banach space theory. An'operator space'is simply a Banach space with an embedding into …

Connections between Banach space theory and classical operator theory on Hilbert space
are multifold. First, one can generalize notions and results involving linear operators on a …

This book provides a comprehensive exposition of M-ideal theory, a branch ofgeometric
functional analysis which deals with certain subspaces of Banach spaces arising naturally in …

These notes revolve around three similarity problems, appearing in three different contexts,
but all dealing with the space B (H) of all bounded operators on a complex Hilbert space H …

The main purpose of this monograph is to report on recent developments in the field of
matrix inequalities, with emphasis on useful techniques and ingenious ideas. Among other …

Commuting maps on a class of algebras called triangular algebras are investigated. In
particular, sufficient conditions are given such that every commuting map L on such an …

Direct digital design of general multirate sampled-data systems is considered. To tackle
causality constraints, a new and natural framework is proposed using nest operators and …
