Sobolev Spaces of Fractional Order, Nemytskij Operators, and Nonlinear Partial Differential Equations

„The book is again an impressive proof of the incredible scientific activity of the Jena school, contributing to functional analysis, operator theory, nonlinear analysis, and differential equations. It will certainly become a standard reference for all specialists working in one of these fields, and it should be found at least in every math library.“ Zentralblatt für Mathematik
