PARTIAL DIFFERENTIAL EQUATIONS - UC Santa Barbara
Some examples of ODEs are: u0(x) = u u00+ 2xu= ex u00+ x(u0)2+ sinu= lnx In general and ODE can be written as F(x;u;u0;u00;:::) = 0 In contrast to ODEs a partial di erential equation (PDE) contains partial derivatives of the depen- dent variable which is an unknown function in more than one variable x;y;::: |

NOTES ON THE EXISTENCE AND UNIQUENESS THEOREM FOR - Madison
existence and uniqueness theorem for (1 1) we just have to establish that the equation (3 1) has a unique solution in [x0 ?hx0 +h] IV Proof of the uniqueness part of the theorem Here we show that the problem (3 1) (and thus (11)) has at most one solution (we have not yet proved that it has a solution at all) |

What is a partial differential equation?
- 1 Introduction 1.1 Preliminaries A partial differential equation (PDE) describes a relation between an unknown function and its partial derivatives. PDEs appear frequently in all areas of physics and engineering.
What are the properties of a partial dierential equation?
- There are a number of properties by which PDEs can be separated into families of similar equations.The two main properties areorderandlinearity. Order. The order of a partial dierential equation is the order of the highest derivative entering theequation.
What is a Dening property of an ordinary dierential equation?
- Recall that an ordinary dierential equation (ODE) contains an independent variablexand a dependentvariableu, which is the unknown in the equation. The dening property of an ODE is that derivativesof the unknown functionu0 =duenter the equation.
What is an ordinary dierential equation?
- The dening property of an ODE is that derivativesof the unknown functionu0 =duenter the equation. Thus, an equation that relates the independentdxvariablex, the dependent variableuand derivatives ofuis called anordinary dierential equation.
