Introduction to the Koopman Operator in Dynamical Systems and Control Theory

2020
This introductory chapter provides an overview of the Koopman operator framework. We present basic notions and definitions, including those related to the spectral properties of the operator. We also review numerical methods that are used to represent the operator on a finite-dimensional basis and to compute its spectral properties from data (DMD ...

Use of matroid theory in operations research, circuits and systems theory

International Journal of Systems Science, 1981
Abstract Recent trends in application of matroid theory to systems problems in operations research and other fields of engineering science are surveyed. Most of the significant applications have been developed in recent years in Japan, and they are connected with that part of matroid theory which deals with the minimum-weight maximum-cardinality ...

Causality, operators and finality in systems theory

AIP Conference Proceedings, 1998
Causal operators acting, by definition, on the past and present functions of time are first presented. Then are described dynamic systems involving a causal operator in their evolution equation, both in the cases of a continuous and a discrete time. A first example of causal dynamic system is given by the modelling of a subject observing an object (Von

Polynomial operators in non-linear systems theory

International Journal of Systems Science, 1971
The concept of generalized polynomial operators is introduced and applied to the theory of non-linear systems. Several properties similar to those previously derived for systems described e.g. by Volterra functional series are studied. The main attention is given to inverting of the operators in question.

A theory of shift operators with applications to nonharmonic systems

International Journal of Quantum Chemistry, 2001
AbstractWe present a theory of shift operators (i.e., operators which shift given solutions into other solutions), including their relationship with deformed algebras and describe a general constructive method which enables us to calculate such operators for a wide class of problems.

On applications of the spectral theory of the Koopman operator in dynamical systems and control theory

2015 54th IEEE Conference on Decision and Control (CDC), 2015
Recent contributions have extended the applicability of Koopman operator theory from dynamical systems to control. Stability theory got reformulated in terms of spectral properties of the Koopman operator [1], providing a nice link between the way we treat linear systems and nonlinear systems and opening the door for the use of classical linear e.g ...

Coupled operator systems and multiparameter spectral theory

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1978
SynopsisIn this paper a spectral theory for completely coupled linear operator systems is developed. These systems take the formwhere Ak, Bk are n × n matrices with operator entries. Λ is an n × n matrix with complex scalar entries and xk is an n × 1 column vector. The main result is a Parseval equality and expansion theorem.

Theory and Operation of the American Legal System

2004
Both law and medicine are dramatic. Many radio dramas, television shows, and movies are based upon either medicine or law because what physicians and attorneys do is sometimes the stuff of high drama. Court is especially dramatic because a trial is, in a very real sense, a piece of theatre.

System Dynamics as a Structural Theory in Operations Management

Production and Operations Management, 2008
The purpose of the paper is to demonstrate the usefulness of (1) system dynamics as a structural theory for operations management and (2) system dynamics models as content theories in operations management. The key findings are that, although feedback loops, accumulation processes, and delays exist and are widespread in operations management, often ...
