Could someone please explain me what are Möbius transformations, and what do they work for?
Where can I find more info about this?
Thanks in advance.

Möbius transformations, also known as linear fractional transformations, are a type of mathematical function that maps points in the complex plane to other points in the complex plane. They are defined by a formula of the form f(z) = (az + b)/(cz + d), where a, b, c, and d are complex numbers.
Möbius transformations have several important properties, including that they preserve circles and lines, and that they are conformal, meaning they preserve angles. They also have a unique inverse for every transformation.
Möbius transformations have many applications in mathematics, including in complex analysis, geometry, and number theory. They are also used in computer graphics and fractal geometry.
The name "Möbius transformations" comes from the German mathematician August Ferdinand Möbius, who first studied these transformations in the 19th century. They are also sometimes referred to as "conformal automorphisms" or "linear fractional transformations."
While Möbius transformations are primarily used in theoretical mathematics, there are some real-life examples that can be described using these transformations. For instance, the projection of a 3D object onto a 2D plane can be represented by a Möbius transformation. They can also be used to map images onto curved surfaces in computer graphics.
