On the hyperspherical universes, the conformal group and Newton's gravitational field
The theory of the hyperspherical universes \(S_ n\), based on the rotations group \(R_{n+1}\), for \(n=4\) gives the ''special projective relativity'' and the equations of magnetohydrodynamics. Instead, for \(n=5\) we obtain a generalization of the ''conformal relativity'' and an unified theory of matter and electricity based on group theory.
