Abstract: Abstract Riemannian Geometry is a multidimensional generalization of the intrinsic geometry of 2D surfaces in the Euclidean space $$\mathbb{E}^{3}$$ . It studies real smooth manifolds equipped with Riemannian metrics, i.e., collections of positive-definite symmetric bilinear forms ((g ij )) on their tangent spaces which vary smoothly from point to point. The geometry of such (Riemannian) manifolds is based on the line element d s 2 = ∑ i, j g ij dx i dx j . This gives, in particular, local notions of angle, length of curve, and volume.
