چکیده

We present some results concerning Poincar e-Dulac normal forms of dynamical systems which are symmetric under (possibly nonlinear) Lie point transformations. We show in particular that the vector elds deening the dynamical system and the Lie symmetry can be put into a "joint normal form".

Lie-point Symmetries and Nonlinear Dynamical Systems (symmetry and Approximate Symmetries of Nonlinear Equations: Bifurcations, Center Manifolds, and Normal Form Reduction)

Nonlinear symmetries of nite dimensional dynamical systems are related to nonlinear normal forms and center manifolds in the neighbourhood of a singular point. Certain abstract results can be used algorith-mically to construct the normal forms and/or the center manifold up to a given order in the perturbation expansion. We also argue that for this task, approximate symmetries are as useful as e...

A Diffusion Equation with Exponential Nonlinearity Recant Developments

The purpose of this paper is to analyze in detail a special nonlinear partial differential equation (nPDE) of the second order which is important in physical, chemical and technical applications. The present nPDE describes nonlinear diffusion and is of interest in several parts of physics, chemistry and engineering problems alike. Since nature is not linear intrinsically the nonlinear case is t...

Local Symmetries of Finite Type Hypersurfaces in C

The first part of this paper gives a complete description of local automorphism groups for Levi degenerate hypersurfaces of finite type in C. We also prove that, with the exception of hypersurfaces of the form v = |z|, local automorphisms are always determined by their 1-jets. Using this result, in the second part we describe special normal forms which by an additional normalization eliminate t...

1 0 Ju n 20 02 Symmetries and reversing symmetries of area - preserving polynomial mappings in generalised standard form

We determine the symmetries and reversing symmetries within G, the group of real planar polynomial automorphisms, of area-preserving nonlinear polynomial maps L in generalised standard form, L : x = x + p1(y) , y ′ = y + p2(x ) , where p1 and p2 are polynomials. We do this by using the amalgamated free product structure of G. Our results lead to normal forms for polynomial maps in generalised s...
