HoppensteadtSpringer[...]... ergodic theories for dynamical systems and random processes, and Poincar´ had a clear image of the chaotic behavior e of dynamical systems that occurs when stable and unstable manifolds cross The book of Genesis begins with chaos, and philosophical discussions about it and randomness continue to this day For the most part, the word chaos is used here to indicate behavior of solutions to mathematical... conversely, computer simulations can help with mathematical analysis New computerbased methods are being derived with parallelization of computations, simpliﬁcation of models through automatic preprocessing, and so on, and the future holds great promise for combined work of mathematical and computer-based analysis There have been many successes to date, for example the discovery and analysis of solitons The... reactions) and small quantities (e.g., trace-element calculations) Computer simulation replaces much of the work formerly done by mathematicians (often as graduate students), and sophisticated software packages are increasing simulation power Simulations illustrate solutions of a mathematical model by describing a sample trajectory, or sample path, of the process Sample paths can be processed in a variety of. .. uniqueness, and stability, about their solutions And then well executed computer algorithms and visualizations provide further qualitative and quantitative information about solutions The computer simulations presented here describe and illustrate several critical computer experiments that produced important and interesting results Analysis and computer simulations of mathematical models are important parts of. .. problems grew out of methods for linear problems, so mastery of linear problems is essential for understanding nonlinear ones Section 1.1 presents several examples of physical systems that are analyzed in this book In Sections 1.2 and 1.3 we study linear systems where A is a matrix of constants In Sections 1.4 and 1.5 we study systems where A is a periodic or almost-periodic matrix, and in Section 1.6... pendulum from rest (down) 1.2 Time-Invariant Linear Systems Systems of linear, time-invariant diﬀerential equations can be studied in detail Suppose that the vector of functions x(t) ∈ E N satisﬁes the system of diﬀerential equations dx = Ax dt for a ≤ t ≤ b, where A ∈ E N ×N is a matrix of constants Systems of this kind occur in many ways For example, time-invariant linear nth-order diﬀerential equations... understanding physical and biological phenomena The knowledge created in modeling, analysis, simulation, and visualization contributes to revealing the secrets they embody The ﬁrst two chapters present background material for later topics in the book, and they are not intended to be complete presentations of Linear Systems (Chapter 1) and Dynamical Systems (Chapter 2) There are many excellent texts and. .. Russian and Ukrainian workers led by Liapunov, Bogoliubov, Krylov, and Kolmogorov developed novel approaches to problems of bifurcation and stability theory, statistical physics, random processes, and celestial mechanics Fourier’s and Poincar´’s work on mathematical physics and dye namical systems continues to provide new directions for us, and the U.S Introduction xv mathematicians G D Birkhoﬀ and N... stability methods for studying nonlinear systems Particularly important for later work is the method of stability under persistent disturbances The remainder of the book deals with methods of approximation and simulation First, some useful algebraic and topological methods are described, followed by a study of implicit function theorems and modiﬁcations and generalizations of them These are applied to several... probability theory, and to the dynamics of physical and biological systems in oscillatory environments We describe here multitime methods, Bogoliubov’s transformation, and integrable systems methods Finally, the method of quasistatic-state approximations is presented This method has been around in various useful forms since 1900, and it has been called by a variety of names—the method of matched asymptotic . results. Analysis and computer simulations of mathematical models are im- portant parts of understanding physical and biological phenomena. The knowledge created in modeling, analysis, simulation, and. algebraic and topological methods are de- scribed, followed by a study of implicit function theorems and modiﬁcations and generalizations of them. These are applied to several bifurcation prob- lems resulted in ergodic theories for dynamical systems and random processes, and Poincar´e had a clear image of the chaotic behavior of dynamical systems that occurs when stable and unstable manifolds
