Borsuk-Ulam Theorem for torus. - Mathematics Stack Exchange
In mathematics, the Borsuk–Ulam theorem states that every continuous function from an n-sphere into Euclidean n-space maps some pair of antipodal points to the same point. Here, two points on a sphere are called antipodal if they are in exactly opposite directions from the sphere's center. See more According to Matoušek (2003, p. 25), the first historical mention of the statement of the Borsuk–Ulam theorem appears in Lyusternik & Shnirel'man (1930).

WebTheorem 2 (Borsuk-Ulam). For any continuous function f: Sn! Rn, there is a point x 2 Sn such that f(x) = f(¡x). There are many difierent proofs of this theorem, some of them … WebThe theorem has several formulations, depending on the context in which it is used and its degree of generalization. The simplest is sometimes given as follows: In the plane Every continuous function from a closed disk to itself has at least one fixed point.
