The degree of a cellular map of a rectangle to a three-link band
Yu. A. Shashkin Institute of Mathematics and Mechanics, Ural Branch of the Russian Academy of Sciences
Abstract:
It is known that the degree of a simplicial triangulation map in Sperners lemma is equal to 1. It is proved similarly that the degree of a cellular map of a rectangle to a three-link band is equal to 3.
Keywords:
Sperner's lemma, simplicial map, cellular map of a rectangle.
