|Title:||Normal Forms and Symmetries of Real Hypersurfaces of Finite Type in C²||Contributor(s):||Ezhov, Vladimir (author); Kolar, Martin (author); Schmalz, Gerd (author)||Publication Date:||2013||DOI:||10.1512/iumj.2013.62.4833||Handle Link:||https://hdl.handle.net/1959.11/14042||Abstract:||We give a complete description of normal forms for real hypersurfaces of finite type in C² with respect to their holomorphic symmetry algebras. The normal forms include refined versions of the constructions by Chern-Moser , Stanton , Kolář . We use the method of simultaneous normalisation of the equations and symmetries that goes back to Lie and Cartan. Our approach leads to a unique canonical equation of the hypersurface for every type of its symmetry algebra. Moreover, even in the Levi-degenerate case, our construction implies convergence of the transformation to the normal form if the dimension of the symmetry algebra is at least two. We illustrate our results by explicitly normalising Cartan's homogeneous hypersurfaces and their automorphisms.||Publication Type:||Journal Article||Grant Details:||ARC/DP130103485||Source of Publication:||Indiana University Mathematics Journal, 62(1), p. 1-32||Publisher:||Indiana University||Place of Publication:||United States of America||ISSN:||0022-2518||Field of Research (FOR):||010111 Real and Complex Functions (incl Several Variables)||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 135
