In mathematics , an ordinary differential equation ODE is a differential equation containing one or more functions of one independent variable and the derivatives of those functions. A linear differential equation is a differential equation that is defined by a linear polynomial in the unknown function and its derivatives, that is an equation of the form. Among ordinary differential equations, linear differential equations play a prominent role for several reasons. Most elementary and special functions that are encountered in physics and applied mathematics are solutions of linear differential equations see Holonomic function. When physical phenomena are modeled with non-linear equations, they are generally approximated by linear differential equations for an easier solution. The few non-linear ODEs that can be solved explicitly are generally solved by transforming the equation into an equivalent linear ODE see, for example Riccati equation. Some ODEs can be solved explicitly in terms of known functions and integrals.
A differential equationis an equation which contains one or more terms which involve the derivatives of one variable i. Chapter preview. The research areas of interest for NoDEA include, but are not limited to: deterministic and stochastic ordinary and partial differential equations, The Pascal programs appear Generalized Difference Methods For Differential Equations. Within the safe confine of a formal course in differential equations one can be fairly confiden that most differential equations will have solutions and that solutions of initial-value problems will probably be unique. Chapter 1 of this book, are introduced, together with some of their im-portant and interesting applications, so that the power and beauty of the subject is immediately apparent. Differential equations relate functions of several variables to derivatives of the functions. They are inspired by problems which arise in diverse fields such as biology, fluid dynamics, physics, differential geometry, control theory, materials science, and engineering.
It seems that you're in Germany. We have a dedicated site for Germany. First, we have completely rewritten the section on singular solutions of differential equations. A new section, 2. Our second major change is the addition of a new section, 4. We felt it desirable to give the reader a brief but nontrivial introduction to this important topic. Our third major change is in Section 2.
Teaches techniques for constructing solutions of differential equations in a novel way, often giving readers opportunity for ingenuity. Over exercises are provided and these are starred according to their degree of difficulty. Each chapter begins with a brief discussion of its contents and history, and hints and comments for many problems are given throughout. The book is intended to serve as a text for the postgraduate students of mathematics and applied mathematics. Thus the most fundamental questions are considered in great detail, while of the more special and difficult parts of the theory have the character of a survey. In the selection of material for this book, the author explains basic ideas and methods applicable to the study of differential equations. Written in an accessible style that includes all needed details and steps, Ordinary Differential Equations is an excellent book for courses on the topic at the upper-undergraduate level.
Many real-world phenomena can be modeled mathematically by using differential equations. Population growth, radioactive decay, predator-prey models, and spring-mass systems are four examples of such phenomena. In this chapter we study some of these applications.
