What would an explicit or analytic formula for a homeomorphism between a circle and a square be?
Or a disc and [0,1] x [0,1]?
Or a disc and [0,1] x [0,1]?
I would try converting the euclidean ball to the infinity norm ball.ex-xian said:What would an explicit or analytic formula for a homeomorphism between a circle and a square be?

A homeomorphism is a type of function in mathematics that describes a continuous and bijective mapping between two topological spaces. In simpler terms, it is a way to describe a transformation that preserves the structure and relationship of points in a space.
An explicit formula for a homeomorphism is a direct and specific equation that can be used to map points from one space to another. An analytic formula, on the other hand, involves using a series of steps or calculations to determine the mapping between points. Both types of formulas can be used to describe a homeomorphism, but they differ in their approach and level of complexity.
Homeomorphisms are useful in many areas of mathematics, particularly in topology and geometry. They allow for the comparison and analysis of different spaces by preserving their underlying structure. Homeomorphisms also help in identifying similarities and differences between spaces, making it easier to solve problems and prove theorems.
Yes, a homeomorphism can exist between spaces of different dimensions. As long as the spaces have the same underlying structure and the function preserves this structure, a homeomorphism can be defined between them. However, the specific mapping may be more complex and difficult to visualize in spaces of different dimensions.
While both homeomorphisms and isomorphisms involve mappings between spaces, they differ in the properties they preserve. A homeomorphism preserves the topological properties of a space, while an isomorphism preserves algebraic properties. In other words, a homeomorphism focuses on the shape and structure of a space, while an isomorphism focuses on the mathematical operations and relationships within a space.
