Many of the modern variational problems of topology arise in different but overlapping fields of scientific study: mechanics, physics and mathematics. In this w

Symmetry has a strong impact on the number and shape of solutions to variational problems. This has been observed, for instance, in the search for periodic solu

This book bridges a gap between a rigorous mathematical approach to variational problems and the practical use of algorithms of structural optimization in engin

This unique book focuses on critical point theory for strongly indefinite functionals in order to deal with nonlinear variational problems in areas such as phys

From its origins in the minimization of integral functionals, the notion of variations has evolved greatly in connection with applications in optimization, equi
