n mathematics, an ordinary differential equation (abbreviated ODE) is an equation containing a function of one independent variable and its derivatives. There are many general forms an ODE can take, and these are classified in practice (see below). The derivatives are ordinary because partial derivatives only apply to functions of many independent variables (see Partial differential equation).
We have attempted to write a concise modern treatment of differential equations
emphasizing applications and containing all the core parts of a course in differential
equations.Asemester or quarter course in differential equations is taught to most engineering
students (and many science students) at all universities, usually in the second
year. Some universities have an earlier brief introduction to differential equations and
others do not. Some students will have already seen some differential equations in
their science classes.We do not assume any prior exposure to differential equations.
In recent years the study of numerical methods for solving ordinary differential equations has seen many new developments. This second edition of the author's pioneering text is fully revised and updated to acknowledge many of these developments. It includes a complete treatment of linear multistep methods whilst maintaining its unique and comprehensive emphasis on Runge-Kutta methods and general linear methods.
Although the specialist topics are taken to an advanced level, the entry point to the volume as a whole is not especially demanding.

Problems involving ordinary differential equations (ODEs) can always be reduced to the study of sets of ﬁrst-order differential equations. For example the second-order equation dy d2 y = r(x) + q(x) 2 dx dx can be rewritten as two ﬁrst-order equations dy = z(x) dx dz = r(x) − q(x)z(x) dx
The three texts in this one cover, entitled ‘The series solution of second order, ordinary differential equations and special
functions’ (Part I), ‘An introduction to Sturm-Liouville theory’ (Part II) and ‘Integral transforms’ (Part III), are three of
the ‘Notebook’ series available as additional and background reading to students at Newcastle University (UK).
The present volume, compiled in honor of an outstanding historian of science,
physicist and exceptional human being, Sam Schweber, is unique in assembling
a broad spectrum of positions on the history of science by some of its leading
representatives. Readers will find it illuminating to learn how prominent authors
judge the current status and the future perspectives of their field. Students will find
this volume helpful as a guide in a fragmented field that continues to be dominated
by idiosyncratic expertise and still lacks a methodical canon.

The goal of this book is to expose the reader to modern computational tools for
solving differential equation models that arise in chemical engineering, e.g.,
diffusion-reaction, mass-heat transfer, and fluid flow. The emphasis is placed
on the understanding and proper use of software packages. In each chapter we
outline numerical techniques that either illustrate a computational property of
interest or are the underlying methods of a computer package. At the close of
each chapter a survey of computer packages is accompanied by examples of
These two texts in this one cover, entitled ‘An introduction to the standard methods of elementary integration’ (Part I)
and ‘The integration of ordinary differential equations’ (Part II), are two of the ‘Notebook’ series available as additional
and background reading to students at Newcastle University (UK). This pair constitutes a basic introduction to both
the elementary methods of integration, and also the application of some of these techniques to the solution of standard
ordinary differential equations.
A differential equation is an ordinary differential equantion if the unknown function depends on only one independent variable. If the unknown function depends on two or moer indenpendent variable, the differential equation is a partial differential equation.
Note that for compatibility with bsstep the arrays y and d2y are of length 2n for a system of n second-order equations. The values of y are stored in the ﬁrst n elements of y, while the ﬁrst derivatives are stored in the second n elements.
MULTIPLICITY RESULTS FOR A CLASS OF ASYMMETRIC WEAKLY COUPLED SYSTEMS OF SECOND-ORDER ORDINARY DIFFERENTIAL EQUATIONS
FRANCESCA DALBONO AND P. J. MCKENNA Received 1 November 2004
We prove the existence and multiplicity of solutions to a two-point boundary value problem associated to a weakly coupled system of asymmetric second-order equations. Applying a classical change of variables, we transform the initial problem into an equivalent problem whose solutions can be characterized by their nodal properties.
This book is based on lectures delivered over the years by the author at the
Universit´e Pierre et Marie Curie, Paris, at the University of Stuttgart, and at
City University of Hong Kong. Its two-fold aim is to give thorough introductions
to the basic theorems of differential geometry and to elasticity theory in
The treatment is essentially self-contained and proofs are complete.
