摘要
研究球面上Fourier-Laplace级数的临界阶Cesaro平均的收敛问题.建立了Dini型.Dini-Lipschtz型,Lebesgue型及Salem型的收敛判别法.
The convergence problem of the Cesaro means of critical order of Fourier- Laplace series on sphere is investigated. The convergence tests of Dini type,Dini-Lipschitz type, Lebesgue type and Salem type are established.
