Nonlinear Functional Analysis and Its Applications

This book consists of nine papers covering a number of basic ideas concepts and methods of nonlinear analysis as well as some current research problems. Thus the reader is introduced to the fascinating theory around Brouwers fixed point theorem to Granas theory of topological transversality and to some advanced techniques of critical point theory and fixed point theory. Other topics include discontinuous differential equations new results of metric fixed point theory robust tracker design problems for various classes of nonlinear systems and periodic solutions in computer virus propagation models.
