A uniqueness result for graphs of least gradient
---------------------------------------------
Our next speaker will be Dr. Lisa Beck (SNS-Pisa) Wednesday December 2
at 17 in Aula Riunioni (Dipartimento di Matematica)
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).
