Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dirichlet可改进性与齐性空间中的等分布
丢番图逼近 Dirichlet可改进性 齐性空间中 等分布
2023/4/24
丢番图逼近中经典的Dirichlet逼近定理给出了用有理向量逼近给定实向量时误差与分母之间的关系。1969年前后，Davenport和Schmidt定义了Dirichlet可改进向量，这些实向量被有理向量逼近时误差比Dirichlet逼近定理给出的更小；他们证明了这些向量构成了R^n中的一个Lebesgue零测集，并提出了如下问题：R^n中光滑曲线上的Dirichlet可改进向量是否仍然是零测的。...
