Good book on Partial Differential Equations

Question

I know that this question was already asked. But I am looking for a book on partial differential equations that covers the basics . And specifically explains reduction to canonical forms with examples.

Answer 1

V. I. Arnold Lectures on Partial Differential Equations

Answer 2

Take a look at Partial Differential Equations in Mechanics 1 by A. P. S. Selvadurai.

This book

• covers the basics in chapters 2 and 3.
• explains reduction to canonical forms in Section 4.2.
• gives examples in Section 4.3.
