Riemannian (not comparable)
- (mathematics) Of or relating to the work, or theory developed from the work, of German mathematician Bernhard Riemann, especially to Riemannian manifolds and Riemannian geometry.

- Similarly, is represented by the closed differential form
- where is the Riemannian curvature of the metric , regarded as an -valued two form, and is the Pfaffian, which is an invariant polynomial defined on the Lie algebra of skew symmetric matrices in even dimensions.
- Similarly, is represented by the closed differential form

- As the preferred metrics applied to symplectic forms are Kähler metrics one could ask for the Riemannian structure which would make the cone with the metric together with the symplectic form into a Kähler manifold. Then and define a complex structure . Alternatively, one could ask for a Riemannian metric on which would define a Kähler metric on via a Riemannian submersion.

- The object of this appendix is to give a summary of known results on 1-dimensional oriented Riemannian Foliations.

- (music) Relating to the musical theories of German theorist Hugo Riemann, particularly his theory of harmony, which is characterised by a system of "harmonic dualism".

- And not only theory: most central European composers of this century were schooled in Riemannian doctrine of one type or another.

- Or take, for example, the rehabilitation by late-twentieth-century North American theorists of Riemannian Tonnetze as a means to navigate the voice-leading intricacies of much chromatic and post-chromatic music.

- The paper connects two notions originating from different branches of the recent mathematical music theory: the neo-Riemannian Tonnetz and the property of well-formedness from the theory of the generated scales.
