Learning Differential Equations with Maple UPDATE on January 7, 2000, I changed the Maple worksheets to Version 5 format. Over a period of several years I wrote and rewrote a set of Maple .mws files for use by my students in an introductory class in Ordinary Differential Equations. The files consist of a series of interactive readings on using Maple to learn a particular DE topic. Associated with each reading file is another file of exercises on the topic. If you examine these files, you will see that they amount to rather more than the usual set of laboratory exercises such as are available in several commercial workbooks. My intent in these lessons is to use Maple to teach differential equations techniques, rather than to teach about using Maple. On the other hand, the persistent student who works through these lessons will surely become an expert at using Maple. To obtain a copy of the shareware click on Maple files for DE Load this file into the directory you want to use and run de.exe. It will explode into about 80 files. The files are in DOS format; however, they can easily be imported into a Macintosh machine (and probably others). You will probably need to use a DOS machine to run de.exe. If your web server cannot accomodate this transfer, you can obtain the file at ftp://ftp.uidaho.edu/pub/ibmpc/math/.

ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 35: Partial differential equations Introduction Like ordinary differential equations, partial differential equations are equations to be solved in which the unknown element is a function, but in PDEs the function is one of several variables, and so of course the known information relates the function and its partial derivatives with respect to the several variables. Again, one generally looks for qualitative statements about the solution. For example, in many cases, solutions exist only if some of the parameters lie in a specific set (say, the set of integers). Various broad families of PDE's admit general statements about the behaviour of their solutions. This area has a long-standing close relationship with the physical sciences, especially physics, thermodynamics, and quantum mechanics: for many of the topics in the field, the origins of the problem and the qualitative nature of the solutions are best understood by describing the corresponding result in physics, as we shall do below. Roughly corresponding to the initial values in an ODE problem, PDEs are usually solved in the presence of

ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 34: Ordinary differential equations Introduction Ordinary differential equations are equations to be solved in which the unknown element is a function, rather than a number, and in which the known information relates that function to its derivatives. Few such equations admit an explicit answer, but there is a wealth of qualitative information describing the solutions and their dependence on the defining equation. There are many important classes of differential equations for which detailed information is available. Applications to engineering and the sciences abound. Numerical solutions are actively studied. History Applications and related fields Note that every indefinite integration problem is really an example of a differential equation, so the entirety of section 28: Integration and Measure is subsumed in this section in principle. The solutions to many classic differential equations, particularly linear second-order differential equations, cannot be expressed in terms of the elementary functions but are themselves studied in 33: Special Functions . This includes Bessel functions, Whittaker functions, Airy functions, and so on.

94. Differential Equations History of differential equations. differential equations are an integral part or a goal of many undergraduate calculus courses. http://occawlonline.pearsoned.com/bookbind/pubbooks/thomas_awl/chapter1/medialib

History of Differential Equations In many ways, differential equations are the heart of analysis and calculus, two of the most important branches of mathematics for over the past 300 years. Differential equations are an integral part or a goal of many undergraduate calculus courses. As an important mathematical tool for the physical sciences, the differential equation has no equal. So it is widely accepted that differential equations are important in both applied and pure mathematics. The history of this subject is rich in its development, and that's what we look at here. The foundations of this subject seem to be so dominated by the contributions of one man, Leonhard Euler , that one could say the history of this subject starts and ends with him. Of course, that would be a gross simplification of its development. There are many important contributors, and those who came before Euler were necessary so that Euler could understand the calculus and analysis necessary to develop many of the fundamental ideas. The contributors after Euler have both refined his work and forged entirely new ideas, inaccessible to Euler's 18

The code GAMD is a generalization of GAM for the solution of Differential Algebraic Equations of index less than or equal to 3 in the form M y' = f(x,y), with a given initial condition. The methods used in both codes are in the class of Boundary Value Methods (BVMs), namely the Generalized Adams Methods (GAMs) of order 3,5,7,9 with step size control References F.IAVERNARO, F.MAZZIA, Block-Boundary Value Methods for the solution of Ordinary Differential Equation.

99. Michael Holst (mholst@math.ucsd.edu) Numerically approximates the solutions of linear and nonlinear elliptic partial differential equations in threedimensional (logically) brick-like domains in an efficient and robust way. PMG employs a non-uniform Cartesian mesh of the user's choice, box-methods or finite element methods for discretization, algebraic (or geometric) construction of lower-dimensional subspace problems, damped-inexact Global Newton methods for nonlinearities, and a jacobian multilevel iteration based on the algebraic (or geometric) subspace hierarchy. There is a sequential Fortran 77 version and a parallel C++ version. By Michael Holst. http://scicomp.ucsd.edu/~mholst/codes/pmg/index.html

PMG = Parallel algebraic MultiGrid Overview PMG is an algebraic multilevel code written in several languages (FORTRAN, C, C++, and CC++). The original FORTRAN/C/C++ versions were written for sequential computers, whereas the more recent CC++ port is a distributed memory parallel implementation. All of the versions of PMG are designed to numerically approximate the solutions of linear and nonlinear elliptic partial differential equations in three-dimensional (logically) brick-like domains in an extremely efficient and robust way. To accomplish this task, PMG employs a non-uniform Cartesian mesh of the user's choice, box-methods or finite element methods for discretization, algebraic (or geometric) construction of lower-dimensional subspace problems, damped-inexact Global Newton methods for nonlinearities, and a jacobian multilevel iteration based on the algebraic (or geometric) subspace hierarchy. The code is applicable to three-dimensional nonlinear Poisson-like scalar equations, allowing for nonlinearities that depend on the scalar unknown (but not on derivatives); nonlinearities of this type occur in the Poisson-Boltzmann equation as well as in other applications, such as the drift-difussion equations in semiconductor modeling. The class of problems for which the code is applicable can be extended with suitable modifications to the code (the methods need not be modified). For strongly elliptic equations with self-adjoint differential operators and smooth coefficients, the solution method is provably optimal (meaning O(N), where N mesh points are used on the finest user-specified mesh). For strongly elliptic self-adjoint operators with simple coefficient discontinuities, the solution method is provably O(N log N). For strongly elliptic self-adjoint operators with arbitrary discontinuities, the solution method is provably convergent, and emperically appears to retain the O(N log N) behavior.
