An Extremely Simple Proof of the K-K-M-S Theorem

An extremely simple proof of the K-K-M-S Theorem is given involving only Brouwer's fixed point theorem and some elementary calculus. A function is explicitly given such that a fixed point of it yields an intersection point of a balanced collection of sets together with balancing weights. Moreover, any intersection point of a balanced collection of sets together with balancing weights corresponds to a fixed point of the function. Furthermore, the proof can be used to show [pi]balanced versions of the K-K- M-S Theorem, with 1T-balancedness as introduced in Billera (1970). The proof makes clear that the conditions made with respect to [pi] by Billera can be even weakened.
