巴拿赫空间中的丢番图逼近

Diophantine approximation in Banach spaces

Lior Fishman, David S. Simmons, Mariusz Urbański

摘要:

本文将同时丢番图逼近理论推广到无限维。此外,我们讨论狄利克雷型定理在一个非常一般的框架,并定义它意味着这样一个定理是最优的。我们表明,最优性是隐含的,但并不意味着存在严重的逼近点。

英文摘要:

In this paper, we extend the theory of simultaneous Diophantine approximation to infinite dimensions. Moreover, we discuss Dirichlet-type theorems in a very general framework and define what it means for such a theorem to be optimal. We show that optimality is implied by but does not imply the existence of badly approximable points.
