Dmitriy Bilyk, Michael T. Lacey, Ioannis Parissis, Armen Vagharshakyan

摘要:

Small Ball不等式是单位正方体中固定体积并矢矩形上Haar函数和的L-无穷范数和的一个几何下界。该猜想是差异论、逼近论和概率论中的基本问题。在这篇文章中,我们集中在一个特殊的情况下的猜想,并给出了最好的已知下界在3维,使用条件期望参数。

英文摘要:

The Small Ball Inequality is a conjectural lower bound on sums the L-infinity norm of sums of Haar functions supported on dyadic rectangles of a fixed volume in the unit cube. The conjecture is fundamental to questions in discrepancy theory, approximation theory and probability theory. In this article, we concentrate on a special case of the conjecture, and give the best known lower bound in dimension 3, using a conditional expectation argument.
