On a compact Lie group $G$ of dimension $n$ , we study the Bochner–Riesz mean $S_{R}^{\unicode[STIX]{x1D6FC}}(f)$ of the Fourier series for a function $f$ . At the critical index $\unicode[STIX]{x1D6FC}=(n-1)/2$ , we obtain the convergence rate for $S_{R}^{(n-1)/2}(f)$ when $f$ is a function in the block-Sobolev space. The main theorems extend some known results on the $m$ -torus $\mathbb{T}^{m}$ .

BOCHNER-RIESZ 均值在紧李群中的块-索博列夫空间
在紧李群上$G$ 维度的$n$ , 我们研究 Bochner-Riesz 均值$S_{R}^{\unicode[STIX]{x1D6FC}}(f)$ 函数的傅里叶级数$f$ . 在关键指数$\unicode[STIX]{x1D6FC}=(n-1)/2$ ,我们得到收敛速度$S_{R}^{(n-1)/2}(f)$ 什么时候$f$ 是块 Sobolev 空间中的函数。主要定理扩展了一些已知的结果$m$ -环面$\mathbb{T}^{m}$ .
