From the stories: "…the e-book encompasses a wealth of fabric necessary to the researcher fascinated by a number of vital variational difficulties and with elliptic partial differential equations. The booklet not just stories the researches of the writer but additionally the contributions of his contemporaries within the comparable and similar fields. The e-book surely turns into a customary reference for researchers in those components. …The e-book is addressed usually to mature mathematical analysts. despite the fact that, any pupil of study can be tremendously rewarded by means of a cautious examine of this book."
M. R. Hestenes in Journal of Optimization concept and Applications
"The paintings intertwines in masterly model result of classical research, topology, and the idea of manifolds and therefore provides a complete treatise of the idea of a number of crucial variational problems."
L. Schmetterer in Monatshefte für Mathematik
"The e-book is especially in actual fact uncovered and comprises the final glossy concept during this area. A complete bibliography ends the book."
