Cohomology with coeﬃcients in the sheaf of holomorphic func-tions is an important tool in the study of Riemann surfaces. This

and principal bundles over the Riemann sphere, due to Grothendieck. The vector bundle version is a very famous result in Algebraic Geometry and is known simply as Grothendieck’s Theorem. However, on the original paper it was a given a more general result for principal 1.1. SIMPLE EXAMPLES; ALGEBRAIC FUNCTIONS 11 Let P(z,w) be a polynomial in two complex variables. We want to think of the equation P(z,w) = 0 as deﬁning w“implicitly” as a function of z.

The Riemann sphere is only a conformal manifold, not a Riemannian manifold. However, if one needs to do Riemannian geometry on the Riemann sphere, the round metric is a natural choice (with any fixed radius, though radius = 1 is the simplest and most common choice).

De Riemann-sfeer, sfeer van Riemann of Riemannbol is in de wiskunde een manier om het complexe vlak met een extra punt op oneindig uit te breiden, zodat anders onbepaalde uitdrukkingen als / = ∞ in bepaalde contexten een zinvolle betekenis krijgen. De Riemann-sfeer is genoemd naar de 19e-eeuwse wiskundige Bernhard Riemann en wordt ook wel aangeduid als 5-11-2019 · Riemann Sphere and Möbius Transformation. In projective geometry, the xy-plane is supplemented by adding an extra line and homogeneous coordinates are introduced to cope with this line at infinity. If points in the plane are described byby a complex number z = x + iy, then, once again, homogeneous coordinates are convenient. A pair (z1, z2) of complex numbers that are not both zero …

The Riemann sphere can be visualized as the complex number plane wrapped around a sphere (by some form of stereographic projection – details are given below).
