仿射形式,分形和施密特游戏的糟糕近似系统

Badly approximable systems of affine forms, fractals, and Schmidt games

Manfred Einsiedler, Jimmy Tseng

摘要:

一个仿射形式的差逼近系统由一个矩阵和一个向量决定。我们表明Kleinbock的猜想的仿射形式的严重逼近系统:对于任何固定的向量,一组严重逼近系统的仿射形式是获胜(在施密特游戏的意义上),即使限制到一个分形(从某个大类的分形)。此外,我们考虑固定矩阵而不是向量,其中模拟语句成立。

英文摘要:

A badly approximable system of affine forms is determined by a matrix and a vector. We show Kleinbock's conjecture for badly approximable systems of affine forms: for any fixed vector, the set of badly approximable systems of affine forms is winning (in the sense of Schmidt games) even when restricted to a fractal (from a certain large class of fractals). In addition, we consider fixing the matrix instead of the vector where an analog statement holds.
