Metric-valued mappings of bounded variation.
This is an interesting survey on the theory and applications of maps of bounded variation with values in an abstract metric (in particular, normed) space. The author discusses interconnections with other classes of maps, discontinuity properties of the variation of a map, and structural properties of the space of all such maps. In the last part he studies various generalizations including multivalued maps and their selections.
