球面函数的Cesàro平均的收敛性与强求和及其逼近阶的研究

the Research on the Convergence, Strong Summability and Approximating Oder of Cesaro Means on Sphere

本文研究了球面上的函数用其Fourier—Laplace级数的一种重要的线性求和法-Cesaro平均来求 和与强求和及其相应的逼近与强逼近的阶的研究状况、发展态势和前景展望等.

In this paper we investigate the researching state, the developing situation and the prospect for the summability , the strong summability and their relevant approximating oder , strong approximating oder of Cesdro mean - an important linear summation process of the Fourier - Laplace series of functions on sphere.
