Characterization of real-analytic infinitesimal CR automorphisms for a class of hypersurfaces in ${\mathbb{C}}^4.$

Cyril Julien, Francine Meylan

In this paper, motivated by the work of Kim and Kolar for the case of pseudoconvex models which are sums of squares of polynomials, we study the Lie algebra of real-analytic infini…
