规范维数是代数结构的整数值不变量。我们最感兴趣的是理解任意域上的半简单仿射代数群下的射影齐次簇的规范维数。回顾了已知的方法、结果、应用和未解决的问题,并提供了一些新的问题。数学学科分类(2010)。初级14L17;次级 14C25。
Canonical dimension is an integral-valued invariant of algebraic structures. We are mostly interested in understanding the canonical dimension of projective homogeneous varieties under semisimple affine algebraic groups over arbitrary fields. Known methods, results, applications, and open problems are reviewed, some new ones are provided. Mathematics Subject Classification (2010). Primary 14L17; Secondary 14C25.
