   Title: A uniqueness result for graphs of least gradient

   Abstract: The focus of this talk is on uniqueness for (generalized)
   minimizers of variational integrals of linear growth. As a model case
   we shall investigate the minimization problem of the integral
                      \int \sqrt{1+|Dw|^2} dx

   in Dirichlet classes of (vector-valued) functions w. It is well known
   that existence of generalized minimizers can be established by
   extending this problem to the space BV of functions of bounded
   variation. We here present a uniqueness theorem for such generalized
   minimizers which was obtained in collaboration with T. Schmidt
   (Erlangen).
