'The authors have presented extremely powerful methods in critical point theory. It can be presumed that researchers in these subjects had been awaiting such an excellent source and here they have it. It is undoubtedly an excellent reference for research scientists in mathematics, physics and engineering.' Dhruba Adhikari, MAA Reviews The present book covers topics that are not easily found elsewhere and it definitely places itself on the research level. The book is very clearly written and presents the material in an efficient way. It will certainly be a valuable tool to researchers, both in the field of abstract critical point theory and in the field of differential equations.
