Abstract
Let A N to be N points in the unit cube in dimension d, and consider the discrepancy function
Here,
and \( \left| {\left[ {0,\vec x} \right)} \right| \) denotes the Lebesgue measure of the rectangle. We show that necessarily
In dimension d = 2, the ‘log L’ term has power zero, which corresponds to a Theorem due to [11]. The power on log L in dimension d ≥ 3 appears to be new, and supports a well-known conjecture on the L 1 norm of D N . Comments on the discrepancy function in Hardy space also support the conjecture.
Резюме
Если d = 2, то степень логарифмического множителя ‘log L’ в классе интегрируемости равна нулю, и нащ результат совпадает в Этом случае с теоремой Халаса 1981 г. В пространствах размерности d ≥ 3 степень логарифма log L в нащей от-сенке, по-видимому, представляет собой новое продвижение в направлении доказательства известной гипотезы о L 1 норме функции D N . Мы приводим и комментарии о функции дискрепанса в пространстве Харди, также в поддержку Этой гипотезы.
