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.

( Š , T ) ( 4.6 ) for all sufficiently small 7. Now this is true for $ € B ( E , p ) by ( 4.4a ) , since u € 0 ( 2 ) , and is true for S E B ( $ , p ) since ...
Hence for sufficiently small T we have r Mn < 1/2 , and conclude from ( 3.20d ) that 2 || Diu || < 2nMr ( 1 + r ) || w || + 21 || Diw || .
