Book Description
It is commonly believed that chaos is linked to non-linearity, however many (even quite natural) linear dynamical systems exhibit chaotic behavior. The study of these systems is a young and remarkably active field of research, which has seen many landmark results over the past two decades. Linear dynamics lies at the crossroads of several areas of mathematics including operator theory, complex analysis, ergodic theory and partial differential equations. At the same time its basic ideas can be easily understood by a wide audience. Written by two renowned specialists, Linear Chaos provides a welcome introduction to this theory. Split into two parts, part I presents a self-contained introduction to the dynamics of linear operators, while part II covers selected, largely independent topics from linear dynamics. More than 350 exercises and many illustrations are included, and each chapter contains a further ‘Sources and Comments’ section. The only prerequisites are a familiarity with metric spaces, the basic theory of Hilbert and Banach spaces and fundamentals of complex analysis. More advanced tools, only needed occasionally, are provided in two appendices. A self-contained exposition, this book will be suitable for self-study and will appeal to advanced undergraduate or beginning graduate students. It will also be of use to researchers in other areas of mathematics such as partial differential equations, dynamical systems and ergodic theory.

Book Description
Designed for advanced engineering, physical science, and applied mathematics students, this innovative textbook is an introduction to both the theory and practical application of linear algebra and functional analysis. The book is self-contained, beginning with elementary principles, basic concepts, and definitions. The important theorems of the subject are covered and effective application tools are developed, working up to a thorough treatment of eigenanalysis and the spectral resolution theorem. Building on a fundamental understanding of finite vector spaces, infinite dimensional Hilbert spaces are introduced from analogy. Wherever possible, theorems and definitions from matrix theory are called upon to drive the analogy home. The result is a clear and intuitive segue to functional analysis, culminating in a practical introduction to the functional theory of integral and differential operators. Numerous examples, problems, and illustrations highlight applications from all over engineering and the physical sciences. Also included are several numerical applications, complete with Mathematica solutions and code, giving the student a "hands-on" introduction to numerical analysis. Linear Algebra and Linear Operators in Engineering is ideally suited as the main text of an introductory graduate course, and is a fine instrument for self-study or as a general reference for those applying mathematics. Contains numerous Mathematica examples complete with full code and solutions Provides complete numerical algorithms for solving linear and nonlinear problems Spans elementary notions to the functional theory of linear integral and differential equations Includes over 130 examples, illustrations, and exercises and over 220 problems ranging from basic concepts to challenging applications Presents real-life applications from chemical, mechanical, and electrical engineering and the physical sciences

Book Description
Linear dynamics is the study of orbits of linear operators on Hilbert spaces (or more general topological vector spaces). If a linear operator has a dense orbit, we say the operator is hypercyclic. One of the fundamental results in linear dynamics is Ansari's Theorem: If a bounded linear operator T is hypercyclic, then for any fixed n natural number, the operator T^n is also hypercyclic. The phenomenon exhibited by Ansari's Theorem is a driving force behind much of the work in this document. This thesis has an introductory chapter and two main chapters. The first main chapter has the goal of extending Ansari's Theorem to actions generated by several commuting linear operators. This goal is realized under the assumption that the action in question is weakly mixing. This chapter also contains several results about semigroups of linear operators on finite dimensional spaces, including a multi-parameter analogue of Ansari's Theorem, and ends with a treatment of affine hypercyclic operators. The second main chapter extends the construction of a probability measure of full support on a Hilbert space which is preserved by a linear operator, to a situation involving the action generated by several commuting operators. Conditions are given that ensure mixing properties of such an action. Following this, we use joint ergodicity to establish some new theorems about joint hypercyclicity, including a theorem which is a variation on both Ansari's Theorem and the related Leon-Muller Theorem. We end the chapter with an example of an operator which is jointly hypercyclic along the polynomial sequences n,n^2,...,n^{d-1}, and yet fails to be hypercyclic along the sequence n^d.
