Query: On a class of variational problems with linear growth and radial
  symmetry   We discuss variational problems on two-dimensional domains with energy
densities of linear growth and with radially symmetric data. The smoothness of
generalized minimizers is established under rather weak ellipticity
assumptions. Further results concern the radial symmetry of solutions as well
as a precise description of their behavior near the boundary.
