关于Fourier-Laplace级数的可和性

About summability of Fourier-Laplace series

Anvarjon Akhmedov

摘要:

本文研究了与Laplace算子自伴扩张有关的展开式的几乎处处收敛性。得到了可和的充分条件。对于Riesz平均阶数大于临界指标$\frac{N-1}{2}$的情形,建立了Riesz平均极大算子的估计.注意当Riesz均值的阶数$α$小于临界指数时,为了建立几乎处处收敛性,需要使用其他方法来证明否定结果。利用单位球面上自伴Laplace-Beltrami算子的谱展开性质,构造了Laplace级数可和性的不同方法

英文摘要:

In this paper we study the almost everywhere convergence of the expansions related to the self-adjoint extension of the Laplace operator. The sufficient conditions for summability is obtained. For the orders of Riesz means, which greater than critical index $\frac{N-1}{2}$ we established the estimation for maximal operator of the Riesz means. Note that when order $α$ of Riesz means is less than critical index then for establish of the almost everywhere convergence requests to use other methods form proving negative results. We have constructed different method of summability of Laplace series, which based on spectral expansions property of self-adjoint Laplace-Beltrami operator on the unit sphere
