| Description | 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 automorphisms are always determined by their 1-jets. Using this result, the second part describes special normal forms which allow to decide effectively about local equivalence of two hypersurfaces given in this normal form. |
