| Popis | We consider the Lie algebra of infinitesimal CR automorphisms of a real hypersurface at a point of Levi degeneracy. As a main result, we give a complete classification of symmetry algebras of dimension at least six for polynomial models of finite Catlin multitype in C-3. As a consequence, this also provides understanding of "exotic" higher order symmetries, which violate 2-jet determination. |
