Variation of Solutions: Partial Differential Equations of the Second Order (Course in Mathematical Analysis, Vol. 3, Part 1)

For the very first time, the final volume in Edouard Goursat's famed Course in Mathematical Analysis is available to English-language readers. Part I covers ordinary and partial differential equations - subjects basic to analysis and applied mathematics and, therefore, very important today - and does so with a fullness that vastly exceeds even that of more recent texts on the subject. The reliability of the coverage by one of the greatest of modern mathematicians makes the book almost indispensable
