Partial Differential Equations
Springer, 1982 - 249 páginas
This book 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 without solutions.

They cannot be given arbitrarily but have to satisfy the compatibility conditions valid on S for all functions regular near S ( instead normal derivatives of order less than m can be given independently from each other ) .
the polynomial P , under which an estimate of the form ( 2.26 ) holds , and hence the initial - value problem can be solved , is : Gårding's hyperbolicity condition . Equation ( 2.14a ) is hyperbolic if there exists a real number c such ...
