# Contact Structures of Partial Differential Equations

### Pieter Thijs Eendebak

In the period 2002-2006 I wrote my Ph.D. thesis "Contact Structures of Partial Differential Equations".
The research was done together with my promotor
prof.dr. J.J. Duistermaat.
On this webpage you can find a short description of the content of the thesis and find the Maple packages used to perform
calculations in the thesis.
The two main themes in my dissertation are *contact structures* and *symmetry methods* for
partial differential equations. The two classes of partial differential equations that are studied in my dissertation are the first order systems for two functions of the variables and the second order scalar equations in
two variables.

A PDF file with my dissertation: Contact Structures of Partial Differential Equations (revised version). The thesis is also available on the University library Igitur. The ISBN number for the thesis is: ISBN-10: 90-393-4435-3, ISBN-13: 978-90-393-4435-4. A BibTex entry can be found here. A list with corrections.
