structures in nonlinear partial differential equations and 'intrinsic localized modes' and 'discrete breathers' in extended lattice systems. The Mathematica (TM)

Here and are parameters, is a dependent variable, and is an independent variable. The discretization of equations (1) and (2) are, , with , where is the gamma function. Three things: The IC p[0] == 0 makes p[t] a scalar; should it be a matrix? The operator * does elementwise multiplication; you probably want matrix multiplication . (Dot).You probably need an explicit matrix for H, too.. Finally, I'm not sure DSolve is even programmed to solve a properly coded matrix ODE in terms of a matrix-valued variable p.NDSolve can solve them numerically, provided the The purpose of this book is to provide the reader with a comprehensive introduction to the applications of symmetry analysis to ordinary and partial differential equations. The theoretical background of physics is illustrated by modem methods of computer algebra.

Fact is, after you read the book you may understand what Ordinary Differential Equations are all about. "By the way there is nothing ordinary about Differential equations". PDF | An overview of the solution methods for ordinary differential equations in the Mathematica function DSolve is presented. | Find, read and cite all the research you need on ResearchGate Differential Equations 1.1 Introduction Let u = u(q,, 2,) be a function of n independent variables z1,, 2,. A Partial Differential Equation (PDE for short) is an equation that contains the independent variables q , , Xn, the dependent variable or the unknown function u and its partial derivatives up to some order.

First, we introduce and discuss the topics covered in typical undergraduate and beginning graduate courses in ordinary and partial differential equations including topics such as Laplace transforms, Fourier series, eigenvalue problems, and boundary-value problems. Differential Equations with Mathematica presents an introduction and discussion of topics typically covered in an undergraduate course in ordinary differential equations as well as some supplementary topics such as Laplace transforms, Fourier series, and partial differential equations. I'm trying to force Mathematica to implicitly differentiate an ellipse equation of the form: x^2/a^2+y^2/b^2 == 100 with a = 8 and b = 6.

## Differential Equations. The Wolfram Language can find solutions to ordinary, partial and delay differential equations (ODEs, PDEs and DDEs). DSolveValue takes a differential equation and returns the general solution: (C[1] stands for a constant of integration.) In [1]:=.

The first approach is more hands on, using DSolve and NDSolve to solve a differential equation and then using interactive elements of Mathematica to obtain a dynamic representation of the solution. Differential Equations with Mathematica presents an introduction and discussion of topics typically covered in an undergraduate course in ordinary differential equations as well as some supplementary topics such as Laplace transforms, Fourier series, and partial differential equations.
