Strong Summability of Fourier-Jacobi Series

Zhu Xianjun; Wang Shaofeng; Zhang Pu(Department of Mathematics, Jining Teachers College, Jining 272125, China)  
Denote by the Cesaro means of critical order of Fourier - Jacobi series of function f,which is integrable on [ - 1, 1 ] with the weight function (1 - x)α (1 + x)β,where α,β - 1. The pointwise convegance of strong summability of (f) by its Cesaro means is discussed. The main result extends the known result of Li Zhongkai's.
