"[This] book is well written and some long computations are presented in a convincing manner. This book will surely be useful to specialists in operator theory, as well as to those interested in its applications, especially for the treatment of the determinants associated to Nakano and Orlicz type operators, among others. Graduate students may also be interested in some chapters of this work, in particular those containing improvements of certain classical results."- F.-H. Vasilescu, Mathematical Reviews, August 2017
