What is the use of Riemann surfaces?
The main interest in Riemann surfaces is that holomorphic functions may be defined between them. Riemann surfaces are nowadays considered the natural setting for studying the global behavior of these functions, especially multi-valued functions such as the square root and other algebraic functions, or the logarithm.
What is Riemann surface tennis?
This stage of the game requires members to play a game of table tennis. However, players will not just play table tennis, that would be an act for Savages. Each player will have to hit the ball back and forth and to receive points they must hit the soma on the court. Hit the soma and you earn 15 points.
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.

What is a branch cut in complex analysis?
A branch cut is a curve (with ends possibly open, closed, or half-open) in the complex plane across which an analytic multivalued function is discontinuous. For convenience, branch cuts are often taken as lines or line segments. Instead, lines of discontinuity must occur.
What is removable singularity and essential singularity?
Definition 17.8 a removable singularity, if lim z → a f ( z ) f (z) exists finitely; 2. a pole, if lim z → a f ( z ) = ± ∞ ; 3. an essential singularity, f (z) does not tend to a limit (finite or infinite) as z → a .
Is a branch point a singularity?
Logarithmic branch points are equivalent to logarithmic singularities. Pinch points are also called branch points. It should be noted that the endpoints of branch cuts are not necessarily branch points.
