|Title:||Geometric proofs of the two-dimensional Borsuk-Ulam theorem|
|Abstract:||We give two proofs of the two-dimensional Borsuk-Ulam theorem. One is completely elementary and does not use homology theory or the mapping degree, while the second one makes use of the recent theory of symplectic quasi-states.|
