Normal forms for hypersurfaces of finite type in C^2

We construct normal forms for Levi degenerate hypersurfaces of finite type in $mathbb{C}^2$. As one consequence, an explicit solution to the problem of local biholomorphic equivalence is obtained. Another consequence determ...

Local symmetries of finite type hypersurfaces in C^2.

The paper gives a complete description of local automorphism groups for Levi degenerate hypersurfaces of finite type in C^2. It is also proved that, with the exception of hypersurfaces of the form v = |z|^k local a...

Local equivalence of symmetric hypersurfaces in C^2

The Chern-Moser normal form and its analog on finite type hypersurfaces the local equivalence problem for symmetric Levi degenerate hypersurfaces of finite type in $ mathbb{C}^2$. The results give...

Finite type hypersurfaces with divergent normal form

We consider the convergence problem for normal forms on finite type hypersurfaces in dimension two, constructed in Kolar (Math Res Lett 12:897-910, 2005). Two families of examples of hypersurfaces with divergent no...

Infinitesimal CR automorphisms of hypersurfaces of finite type in ${mathbb{C}}^2$

We study the Chern-Moser operator for hypersurfaces of finite type in $Bbb C^2.$ Analysing its kernel, we derive explicit results on jet determination for the stability group, and give a description of infinitesimal CR auto...

Normal Forms and Symmetries of Real Hypersurfaces of Finite Type in C-2

We give a complete description of normal forms for real hypersurfaces of finite type in C-2 with respect to their holomorphic symmetry algebras. The normal forms of the hypersurface for every type of its s...

Remarks on the Symmetries of a Model Hypersurface

hypersurfaces with polynomial models, as obtained in [30]. We formulate the jet determination results for finitely smooth hypersurfaces of finite type. Another goal of the paper is to gain more understand...

Generalized models and local invariants of Kohn-Nirenberg domains
