“This higher level book will certainly be a useful resource for graduate students and researchers in mathematical modeling of physical systems. The book is recommended for university libraries and research establishments.” (K. N. Shukla, zbMATH 1428.80002, 2020)“The book is not only a useful resource for researchers in applied mathematics, but can also be used as a demanding textbook for graduate students with a solid knowledge in differential geometry and functional analysis.” (Theophanes Grammenos, Mathematical Reviews, July, 2019)
