Outline of Final Research Achievements

We give original researches on the following two maps: (1) stationary maps (we call them C-stationary maps) of the integral of the norm of a tensor which is a scale of the conformality of smooth maps between Riemannian manifolds, (2) stationary maps (we call them symphonic maps) of the integral of the norm of the pullback of metrics by smooth maps between Riemannian manifolds. We obtain results of regularity, a construction (we call it a symphonic join) and stability for symphonic maps. For C-stationary maps, we have partial results of stability, though it is considerably difficult to handle C-stationary maps.
