Harmonic Maps Between Riemannian Polyhedra

This research-level monograph on harmonic maps between singular spaces sets out much new material on the theory bringing all the research together for the first time in one place. Riemannian polyhedra are a class of such spaces that are especially suitable to serve as the domain of definition for harmonic maps. Their properties are considered in detail with many examples being given and potential theory on Riemmanian polyhedra is also considered. The work will serve as a concise source and reference for all researchers working in this field or a similar one.
