The Coxeter Trisection and the Hadwiger Conjecture in Multidimensional Spaces
《Journal of Applied Mathematics and Physics》2024年第12期4301-4321,共21页István Lénárt 
In this article, I consider the right triangle as the simplex in the Euclidean plane, and extend this definition to higher dimensions. The n-dimensional simplex has one hypotenuse and (n−1)legs (catheti). The (n−1)leg...
