Spectra of 912 G- and K -type stars in six galactic directions (⁠lII=90∘,bII=±20∘;lII=180∘,bII=±20∘;lII=90∘,bII=+45∘;bII=+90∘⁠) have been secured. The relevant space motions of the stars, subdivided into distance groups ...

It is shown that the boson representation of infinite-component SO(4,2) wave equations represents a system of four oscillators as well as three-dimensional Kepler dynamics. These two pictures are complementary to each ...
