This monograph treats variational problems for mappings from a surface equipped with a conformal structure into Euclidean space or a Riemannian manifold. Presen

The marriage of analytic power to geometric intuition drives many of today's mathematical advances, yet books that build the connection from an elementary level

In this volume are collected notes of lectures delivered at the First In ternational Research Institute of the Mathematical Society of Japan. This conference, h

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

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