U-统计量的扇形收敛

Sectorial convergence of U-statistics

Anda Gadidov

摘要:

在本文中,我们证明了Z^d_+中以线性扇区为指标的对称化U-统计量的几乎必然收敛到零等价于沿Z^d_+的对角线收敛,正如Lata \la和Zinn [Ann. Probab. 28(2000)1908-1924]。多指标i.i.d.和的类似结果的比较。还产生了随机变量。

英文摘要:

In this note we show that almost sure convergence to zero of symmetrized U-statistics indexed by a linear sector in Z^d_+ is equivalent to convergence along the diagonal of Z^d_+, as it is considered in Lata\la and Zinn [Ann. Probab. 28 (2000) 1908-1924]. Comparisons with similar results for sums of multi-indexed i.i.d. random variables are also made.
