Partial Differential Equations

From the reviews of the earlier editions:

“An excellent second-reading text. Should be accessible to any mathematician. Highly recommended.” – The Mathematical Gazette

“An excellent text upon which to build and introduction to partial differential equations at the graduate level. In addition...recommended for the nonspecialist.” – American Mathematical Monthly

Partial Differential Equations is a very well accepted introduction to the subject. In it, the author identifies the significant aspects of the theory and explores them with a limited amount of machinery from mathematical analysis. Now, in this fourth edition, the book has again been updated with an additional chapter on Lewy’s example of a linear equation with solutions.
