Some Algebro-Geometrical Aspects of the Newton Attraction Theory,. The set of critical values of its projection on the base space is called the caustic. At the caustic the particle density becomes infinite (mathematically); the caustic is the place where clustering occurs (generation of galaxies and so on).

To state it, recall that such G-orbits correspond to W-orbits in .(.). Then Kostant‘s result is:.(1.1). . a ..

Some Algebro-Geometrical Aspects of the Newton Attraction Theory,s explained by the geometry of caustics of a mapping of a Lagrange submanifold of the symplectic total space of the cotangent bundle to its base space. This Lagrange submanifold is formed by the particle velocities. Contemporary theory of the hot universe predicts a smooth potential velocity field a
