Query: A pointwise characterization of functions of bounded variation on metric
  spaces   We give a new characterization of the space of functions of bounded variation
in terms of a pointwise inequality connected to the maximal function of a
measure. The characterization is new even in Euclidean spaces and it holds also
in general metric spaces.
