From the reviews:

“This book is a collection of 32 articles and is meant as a special tribute to the work of H. Amann of the University Zuerich on the occasion of his retirement. It is an interesting mix at the boundary between pure and applied mathematics. … This is an interesting collection, since it contains papers which one does not see if one is not a specialist and therefore gives a motivating fresh look on certain subjects.” (M. Hofmann-Ostenhof, Monatshefte für Mathematik, Vol. 152 (1), September, 2007)
