# Partial Differential Equations

From Wikibooks, open books for an open world

This Wikibook is UNDER CONSTRUCTION! It will hopefully be completed in the not too distant future.

Some partial differential equations describe important processes in nature. This wikibook shows how to solve different kinds of partial differential equations and/or gives existence and uniqueness results, using a variety of methods.

Authors should be aware of the stylistic guidelines.
