Keywords Infinitesimal CR automorphisms; Finite Catlin multitype; Exotic symmetries
Description We study the infinitesimal CR automorphisms of polynomial model hypersurfaces of finite multitype, which violates 2-jet determination. We give an exposition of some recent results, which provide explicit description of such “exotic” symmetries in complex dimension three. The results are illustrated by numerous examples.
