In 1928 Emanuel Sperner presented a simple. Cohen, On the Sperner lemma, J. Theory 2 1967.Abstract. This paper presents elementary combinatorial proofs of Sperners. Advanced topics like degree theory or homology. Before beginning, it.ple combinatorial result known as Sperners lemma. As motivation, we examine a special case of Sperners lemma.

Engel, Sperner Theory, Encyclopedia of Mathematics and Its Applications 65.We also present the Sperners lemma, a celebrated result in. This famous theorem due to Kakutani 5 is used extensively in game theory. In fact, John Nash.

The discrete yet ubiquitous theorems of Carathéodory, Helly, Sperner, Tucker, and Tverberg
We discuss five discrete results: the lemmas of Sperner and Tucker from combinatorial topology and the theorems of Carathéodory, Helly, and Tverberg from combinatorial geometry. We explore their connections and emphasize their broad impact in application areas such as game theory, graph theory, mathematical optimization, computational geometry, etc.
متن کاملSperner capacities
We determine the asymptotics of the largest family of qualitatively 2{independent k{ partitions of an n{set, for every k > 2. We generalize a Sperner-type theorem for 2{partite sets of KK orner and Simonyi to the k{partite case. Both results have the feature that the corresponding trivial information-theoretic upper bound is tight. The results follow from a more general Sperner capacity theorem...

That is, C operates on n coordinates x1, . . . , xn and outputs a color. We can see how having such a circuit is equivalent to a unique coloring of the cube: if we want to find the color at a vertex, just give the circuit the coordinates of the vertex, and use the output of the circuit. The Sperner problem then becomes the problem of finding a panchromatic simplex when given a coloring circuit ...
متن کاملMorphisms for resistive electrical networks
This paper presents a notion of morphism for resistive electrical networks. It is obvious that symmetries of a resistive network are (trivial) morphisms and easy to show that they induce a nontrivial quotient (their symmetrizer). We extend this result to arbitrary RESNET morphisms having a common domain (called the pushout in category theory). Our principle application of RESNET morphisms is to...
متن کاملExtensions of Sperner and Tucker's lemma for manifolds
The Sperner and Tucker lemmas are combinatorial analogous of the Brouwer and Borsuk Ulam theorems with many useful applications. These classic lemmas are concerning labellings of triangulated discs and spheres. In this paper we show that discs and spheres can be substituted by large classes of manifolds with or without boundary.
