On the other hand, the question of the stability of particular solutions of the Einstein equations in the wake of the groundbreaking proof of the stability of the Minkowski space-time
due to D.
It details the theory of contact and its connection to the theory of caustics and wavefronts, then applies these theories to deduce geometric information about surfaces embedded in three, four, and five-dimensional Euclidean spaces, as well as spacelike surfaces in the Minkowski space-time
. It discusses the basic facts about the extrinsic geometry of submanifolds of Euclidean spaces, singularities of smooth mappings, the theory of contact introduced by Mather and developed by Montaldi, basic concepts in symplectic and contact geometry and the connection to the theory of contact and Lagrangian and Legendrian singularities, and global results on closed surfaces using local invariants obtained from the the local study of surfaces.
At the beginning of the twentieth century Einstein's theory opened a door to new geometries such as Minkowski space-time
, which is simultaneously the geometry of special relativity and the geometry induced on each fixed tangent space of an arbitrary Lorentzian manifold.
Recently, a new special curve is named according to the Sabban frame in the Euclidean unit sphere; Smarandache curve has been defined by Turgut and Yilmaz in Minkowski space-time

Galilean spacetime plays the same role in nonrelativistic physics that Minkowski space-time
does in relativistic physics.
