Abstract. In this chapter we study the dynamics of area-preserving (i.e., symplectic) monotone twist maps of the annulus. While seemingly quite special, we have already seen examples of such maps as time one maps of time periodic Hamiltonian systems of one degree of freedom, as Poincaré section maps for periodic orbits of Hamiltonian systems of two degrees of freedom (see Chapter V, Sections Author: Kenneth R. Meyer, Glen R. Hall. of group invariant/equivariant maps and/or in nite-dimensional input spaces. Our general results in Section 2 are based on classical results of the theory of polynomial invariants (Hilbert [, ], Weyl []). An important element of constructing invariant and equivariant models is the extraction of invariant and equivariant features. This book is ideal for graduate students and researchers working in differential equations, symbolic computation, applications of Lie groups and, to a lesser extent, differential geometry. Reviews 'This book is a very good introduction to Cartan's method of moving frames, using primarily undergraduate calculus. full of good examples.'. MOMENT MAPS AND GEOMETRIC INVARIANT THEORY 3 is identified with a one complex-dimensional representation on which T acts by exp(ξ)α:= exp(2πiα(ξ)). The kernels ker(α) of the roots α∈ R(k) divide tinto a set of (open) Weyl chambers; given a generic linear function on t there is a unique open positive Weyl chamber onCited by: 5.

The book of Sturmfels is both an easy-to-read textbook for invariant theory and a challenging research monograph that introduces a new approach to the algorithmic side of invariant theory. The Groebner bases method is the main tool by which the central problems in invariant theory become amenable to algorithmic solutions.   Try the new Google Books.

It is the exponential map of a canonical right-invariant affine connection on G. This is usually different from the canonical left-invariant connection, but both connections have the same geodesics (orbits of 1-parameter subgroups acting by left or right multiplication) so give the same exponential map.

This book presents an updated version of this theory together with many of the important recent developments. As a text for beginners, this book provides an introduction to the structure and finite. A multitude of physical, chemical, or biological systems evolving in discrete time can be modelled and studied using difference equations (or iterative maps). Here we discuss local and global dynamics for a predator-prey two-dimensional map. The system displays an enormous richness of dynamics including extinctions, co-extinctions, and both ordered and chaotic by: 1. Euclidean area is invariant under a linear map with determinant 1 (see Equi-areal maps). Some invariants of projective transformations: collinearity of three or more points, concurrency of three or more lines, conic sections, the cross-ratio.
