数学中的特例：欧拉示性数、Division Algebras、交叉向量积和Fano拟阵
Some Exceptional Cases in Mathematics: Euler Characteristic, Division Algebras, Cross Vector Product and Fano Matroid
摘要：
我们回顾了在几个数学场景，包括图论，划分代数，向量积形式主义和拟阵理论的显着成果。具体地说，我们提到下列主题：（1）图论中的欧拉关系及其高维推广，（2）除代数的维数定理，特别是赋范除代数的Hurwitz定理，（3）向量向量积维数的可能性，（4）图和拟阵的一些定理。我们的主要目标是激发这四个主题的可能研究工作，对它们可能的联系给予特别关注。
英文摘要：
We review remarkable results in several mathematical scenarios, including graph theory, division algebras, cross product formalism and matroid theory. Specifically, we mention the following subjects: (1) the Euler relation in graph theory, and its higher-dimensional generalization, (2) the dimensional theorem for division algebras and in particular the Hurwitz theorem for normed division algebras, (3) the vector cross product dimensional possibilities, (4) some theorems for graphs and matroids. Our main goal is to motivate a possible research work in these four topics, putting special interest in their possible links.
