Is a torus a Riemann surface?
Is a torus a Riemann surface?
In mathematics, particularly in complex analysis, a Riemann surface is a connected one-dimensional complex manifold. So the sphere and torus admit complex structures, but the Möbius strip, Klein bottle and real projective plane do not.
Is Riemann sphere a Riemann surface?
In geometry, the Riemann sphere is the prototypical example of a Riemann surface, and is one of the simplest complex manifolds.
Are Riemann surfaces orientable?
Riemann surfaces are always orientable, so in the following review we only consider orientable, triangulable compact surfaces M. We assume that the reader has seen the theory of integration on differentiable manifolds. A Riemann surface is a two dimensional real manifold.

What is extended complex plane?
The extended complex plane is the name gives to the complex plane with a point at infinity attached: , where denotes complex infinity. It is also called the Riemann sphere and is various denoted or .
What is complex infinity?
Complex infinity is an infinite number in the complex plane whose complex argument is unknown or undefined. Complex infinity may be returned by the Wolfram Language, where it is represented symbolically by ComplexInfinity. The Wolfram Functions Site uses the notation. to represent complex infinity.
Is the Riemann sphere a field?
I think its most natural algebraic interpretation the Riemann sphere has is its identification with the complex projective line, so that it is a set upon which the Möbius group acts upon. So, not a field, ring or algebra, but the underlying space of a group action.

Bernhard Riemann/Places lived
Georg Friedrich Bernhard Riemann was born on September 17, 1826 in the rural village of Breselenz, in northern Germany. He was the second of his parents’ six children. His mother was Charlotte Ebell, the daughter of a government employee in the city of Hanover.
