The Riemann Sphere. Other geometric contributions made by Riemann include a generalization of the metric of Pythagoras to complex spaces, and the Riemann sphere – both of which deal with the concepts of infinity. Riemann’s sphere is a step up from Bolzano’s principle which shows that there are the same number of infinitely many points. Holomorphic, non-invertible dynamical systems of the Riemann sphere are surprisingly intricate and beautiful. Often the indecomposable, completely invariant sets are fractals (a la Mandelbrot [M1]) because, in fact, they are quasi-self-similar (see Sullivan [S3] and ()).

Riemann surfaces and how they relate to the topology of the surface as reﬂected,forexample,bythegenusinthecompactcase. Elementary results such as the Riemann-Hurwitz formula relating the branch points to the genera of the surfaces are discussed. We then show how to deﬁne Riemann surfaces via discontinuous group actions and give. J. Iglesias, A. Portela, A.

of an analytic function $w = f(z)$ of a complex variable $z$ A surface $R$ such that the complete analytic function $w = f(z)$, which is, in general, multiple-valued, can be considered as a single-valued analytic function $w = F(p)$ of a point $p$ on $R$.. The concept of a Riemann surface arose in connection with the studies of algebraic functions $w = f(z)$ defined by an.

The Riemann sphere can be visualized as the unit sphere x 2 + y 2 + z 2 = 1 in the three-dimensional real space R this end, consider the stereographic projection from the unit sphere minus the point (0, 0, 1) onto the plane z = 0, which we identify with the complex plane by ζ = x + Cartesian coordinates (x, y, z) and spherical coordinates (θ, φ) on the sphere (with θ the zenith.

Since first posed and solved ingreat progress has been achieved in the one-dimensional case. However, the two-dimensional case is substantially different. Although research interest in it has lasted more than a century, it has yielded almost no analytical.

Nicholas McLean Chaotic Dynamics on the Riemann Sphere Rational Functions De nition A rational function is a function of the form R(z) = P(z) Q(z) where P and Q are polynomials with no common factors, not both the zero polynomial.

Intuitively, if P= 0, then R= 0 and if Q= 0, then R= 1. The theory of complex dynamics in one variable, initiated by Fatou and Julia in the early twentieth century, concerns the iteration of a rational function acting on the Riemann sphere.

Building on foundational investigations of $$p$$-adic dynamics in the late twentieth century, dynamics in one non-archimedean variable is the analogous theory.

Randomly drawn $2\\times 2$ matrices induce a random dynamics on the Riemann sphere via the Möbius transformation.

Considering a situation where this dynamics is restricted to the unit disc and given by a random rotation perturbed by further random terms depending on two competing small parameters, the invariant (Furstenberg) measure of the random dynamical system is.

Note that this sphere is not the same as the Riemann sphere, since the latter is merely a stereographic projection of the complex plane onto a sphere rather than a redefinition of complex numbers over the sphere's surface.

The proof of this rigidity theorem involves the natural action of SL 2(R) on the sphere bundle Q 1M g!M g; consisting of pairs (X;q) with q2Q(X) and kqk= 1.
