报告摘要：Harmonic morphisms, mapping which pull back local harmonic functions to harmonic functions, have played an important role in understanding the relation between the geometry and topology of Riemannian manifolds. Various attempts have been made to adapt the notion to other situations. None of these have been satisfactory due to the complexity of the characterizing equations and the lack of examples. In this work, we introduce a new notion of generalized harmonic morphisms that have an elegant characterization which enables the construction of explicit examples, as well as impacting on the theory of biharmonic mappings.
