This paper deals with the CesaÁ ro means of conjugate Jacobi series introduced by Muckenhoupt and Stein and Li. The exact estimates of the norms of the conjugate (C, $) kernel for 0 $ :+ 1 2 are obtained. It is proved that when $>:+ 1 2 , the (C, $) means of the conjugate Jacobi expansion of a funct

✦ Synopsis
Let {Xn; n ~>1} be a sequence of independent real-valued random variables and {a~,k; k/> l,n >~1} an infinite matrix of real numbers with supn/an, k[ <~, k ~> 1. We provide some very general conditions which guarantee that E sup an, kXk < cx~ \ " I*:L I/ for some p >0. This result is used to establish some results on moments of the maximum of normed weighted averages, in particular, the maximum of Cesflro summation. (~
