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. Formally: if 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). The first proof was given by Karol Borsuk (1933), where the … See more • No subset of $${\displaystyle \mathbb {R} ^{n}}$$ is homeomorphic to $${\displaystyle S^{n}}$$ • The ham sandwich theorem: For any See more • In the original theorem, the domain of the function f is the unit n-sphere (the boundary of the unit n-ball). In general, it is true also when the domain of f is the boundary of any … See more The following statements are equivalent to the Borsuk–Ulam theorem. With odd functions A function See more 1-dimensional case The 1-dimensional case can easily be proved using the intermediate value theorem (IVT). Let See more Above we showed how to prove the Borsuk–Ulam theorem from Tucker's lemma.
