unusual facts about Ricci-flat manifold


Ricci-flat manifold

Since Ricci curvature measures the amount by which the volume of a small geodesic ball deviates from the volume of a ball in Euclidean space, small geodesic balls will have no volume deviation, but their "shape" may vary from the shape of the standard ball in Euclidean space.


2010 Catalunya GP2 Series round

Ricci's second place was an equally memorable result for DPR, a team that scored precisely one point between 2007 and 2009, and has not won a race since the inaugural GP2 season in 2005.

Elena Sofia Ricci

Flat manifold

Intuitively, a flat manifold is one that "locally looks like" Euclidean space in terms of distances and angles, e.g. the interior angles of a triangle add up to 180°.

A flat torus can be isometrically embedded in three-dimensional Euclidean space with a C1 map (by the Nash embedding theorem) but not with a C2 map, and the Clifford torus provides an isometric analytic embedding of a flat torus in four dimensions.
