Название: Uniqueness Theorems for Variational Problems by the Method of Transformation Groups
Автор: Reichel W.
Аннотация:
A classical problem in the calculus of variations is the
investigation of critical points of functionals {\cal L} on normed
spaces V. The present work addresses the question: Under what
conditions on the functional {\cal L} and the underlying space V does
{\cal L} have at most one critical point? A sufficient condition for
uniqueness is given: the presence of a
