Query: very bad book

This books contains lecture notes for a course of Moser published after his death in 1999. It is a good examplethat this practise is not very advisable since certainly Moserwould not have been happy with the outcome (the bookhas been edited by a student of his).The book is riddled with a very high number of misprintsand inaccuracies which leaves the impressionthat no one has read the book prior to publication.Many results are misstated and hard to understand(for instance the basic theorem 1.4.4. should be... Assume F_pp\ge 0 on \Omega. Then \gamma^starcan be embedded in an extremal field. ...)The publisher would be well advised to offtake the bookimmediately and publish a carefully corrected versionat a later time.
