Normally flat ring

In algebraic geometry, a normally flat ring along a proper ideal I is a local ring A such that is flat over for each integer . The notion was introduced by Hironaka in his proof of the resolution of singularities as a refinement of and was later generalized by Alexander Grothendieck and others. (Wikipedia).

A beautiful observation of classical physics is that “light travels in straight lines” is only an approximation to reality. More precisely, light always takes a geodesic – a path between two points minimizing its time of travel. While this is often used to explain physical phenomena mathe
