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.

Box 94079, 1090 GB Amsterdam, The Netherlands Obtaining PSIDE The current version of PSIDE is 1.3 (November 25, 1998). PSIDE consists of the following files user.ps.gz or user.pdf PSIDE Users' Guide (gzipped PostScript and PDF version, respectively) pside.f The Fortran 77 source of PSIDE cacm423.f For PSIDE's linear algebra we chose to use LAPACK. However, if you do *not* have available on your system both a machine tuned LAPACK, and a machine optimized BLAS we suggest you use these replacement routines instead of the portable LAPACK implementation. Of course the latter will work, however, it may give much worse performance. vdpol.f an example driver for the Van der Pol problem, an ODE of dimension 2 (as given in the PSIDE Users' Guide) pendul.f

Highlights of this Course This course includes lecture notes assignments problems for group work in recitation , and a full set of lecture videos Course Description Differential Equations are the language in which the laws of nature are expressed. Understanding properties of solutions of differential equations is fundamental to much of contemporary science and engineering. Ordinary differential equations (ODE's) deal with functions of one variable, which can often be thought of as time. Topics include: Solution of first-order ODE's by analytical, graphical and numerical methods; Linear ODE's, especially second order with constant coefficients; Undetermined coefficients and variation of parameters; Sinusoidal and exponential signals: oscillations, damping, resonance; Complex numbers and exponentials; Fourier series, periodic solutions; Delta functions, convolution, and Laplace transform methods; Matrix and first order linear systems: eigenvalues and eigenvectors; and Non-linear autonomous systems: critical point analysis and phase plane diagrams.

Paul's Online Math Notes Welcome to my online math tutorials and notes. The intent of this site is to provide a complete set of online (and downloadable) notes and/or tutorials for classes that I teach here at Lamar University . I've tried to write the notes/tutorials in such a way that they should be accessible to anyone wanting to learn the subject regardless of whether you are in my classes or not. In other words, they do not assume that you've had prior classes here at Lamar University, they instead assume nothing more than a good working background that is required for anyone to learn the subject. The assumptions about your background that I've made are given with each description below. New! I've put a series of Calculus cheat sheets online. They cover most of the material from Calculus I and a small amount of material from Calculus II. I plan on extending them to all of Calculus II and Calculus III when I get the chance. I'd like to thank Fred J. for all the typos that he's found and sent my way! I've tried to proof read these pages and catch as many typos as I could, however it just isn't possible to catch all of them when you are also the person who wrote the material. Fred has caught quite a few typos that I'd missed. Thanks again Fred! If you are one of my current students and are here looking for homework assignments I've got a set of links that will get you to the right pages listed here At present I've gotten the notes/tutorials for my Algebra (Math 1314), Calculus I (Math 2413), Calculus II (Math 2414), Calculus III (Math 2415), Linear Algebra (Math 2318) and Differential Equations (Math 3401) class online.

Software for Initial Value Problems The code GAM numerically solves solves first order ordinary differential equations, either stiff or nonstiff in the form y'=f(x,y), with a given initial condition. 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.

Public Computer Codes Scott R. Fulton This page lists various computer codes which I have written and people have occasionally requested. They are made available on an "as-is" basis, with no promise of suitability, correctness, quality, or support. If you find them useful, I'd appreciate hearing about it. You may use them as part of your work, but if you publish anything based on them, please acknowledge the source. Thanks. Multigrid Control Package This is a collection of Fortran77 routines for executing various multigrid control algorithms, including V-cycles, W-cycles, C-cycles, and the FMG algorithm. All are problem-independent, and can be accessed via a single routine (mgs) which also can execute single-grid relaxation for comparison. The use of this code is illustrated by my Multigrid Poisson Solver listed below. Fortran 77 code: single precision or double precision Multigrid Solver for the 2D Poisson Problem This Fortran77 routine solves the Poisson Problem on a two-dimensional rectangle with Dirichlet boundary conditions via a multigrid method. This uses Gauss-Seidel relaxation (red-black ordering) with half-injection of residuals and bilinear interpolation of corrections in a V-cycle algorithm. It works and is reasonably efficient, but is hardly general-purpose software. I wrote it primarily as an example of a relatively simple approach to programming multigrid methods in Fortran77; this approach separates the problem-dependent and multigrid-specific code and allows the compiler to handle the indexing on rectangular grids. It comes with a simple main program and the V-cycle control algorithm from my Multigrid Control Package listed above.
