Louis Dupaigne is an assistant professor at Université Picardie Jules Verne in Amiens, France.
the author has put every effort into giving complete details of the computations. ... the self-contained one hundred-page long appendices provide a splendid resource for the reader. The material contained there has been chosen with particular good taste and constitutes in itself a valuable source of information. Remarks and further features ... are presented in an `exercise' format. I have found many of them suitably posed and reasonable to work at the level of the book. -Jose C.
