During last 30 years it was supposed that the graded Lie algebra of infinitesimal holomorphic automorphisms of quadric model CR manifold hasn't nontrivial graded components of weight greater than two. Recently it turned out that it is not true. There exist some enigmatic “special” quadrics, whose graded components go further. The author is going to speak about his recent advances in the understanding of this phenomenon.
The main results was obtained with the help of distributions, Fourier transform and the fundamental principle of Ehrenpreis.
