Noncommutative Multivariable Operator Theory

Integral Equations and Operator Theory, 2012
Given a Hilbert space \(\mathcal{H}\), the author studies noncommutative domains \(\mathbb{D}_f^\phi(\mathcal{H})\) in \(B(\mathcal{H})^n\), generated by a positive regular free holomorphic function \(f\) and some classes of \(n\)-tuples \(\phi=(\phi_1,\dots,\phi_n)\) of formal power series in (noncommutative) indeterminates \(Z_1,\dots,Z_n\).

Multivariable Operator Theory

2023
Over the course of his distinguished career, Jörg Eschmeier made a number of fundamental contributions to the development of operator theory and related topics. The chapters in this volume, compiled in his memory, are written by distinguished mathematicians and pay tribute to his many significant and lasting achievements.

Introducing the Operator Theory

2016
The Operator Theory is a new theory about the hierarchical organisation of complexity in nature. The theory is based on the idea that in the space of all possible processes, a small subset exists of highly specific processes through which small objects can integrate to form new, more complex objects.

The RNA Operator Theory

Medical Hypotheses, 1982
The aim of the RNA Operator Theory is to propose a new explanation for the mechanism of certain biological control functions, including morphogenesis and brain function. It assumes the existence of a natural computing language, the vocabulary of which, in machine language form, is constituted of bytes of nucleotide bits.

Operator Theory Preliminaries

1989
In this chapter we present selected results from functional analysis that will be called upon in subsequent chapters. We present only a few basic ideas but we shall make frequent use of these in the sequel. For the reader who is familiar with operator-theoretic formulations of partial differential equations this chapter should provide a useful summary ...

Operator Realization Theory

1998
The realization problem for time-varying systems is to find a (minimal) state space description for the input-output operator of a time-varying system, solely based on the collection of time-varying impulse responses. An important role in its solution is played by the Hankel operator, which is a restriction or suboperator of the input-output operator ...
