limit in the sense of pointwise convergence

Spherical means of radial function and its pointwise convergence;

向径函数的球面平均及其点态收敛性

The pointwise convergence problem of Cesdro means of critical order of Fourier-Laplace series on sphere is discussed in the paper.

研究了球面函数的Fourier—Laplace级数的临界阶Cesaro平均的点态收敛问题,给出了临界阶Cesaro平均收敛的Gergen型判别法。
