Yb. Wang et al., EQUIVALENT CONDITIONS OF COMPLETE CONVERGENCE FOR INDEPENDENT WEIGHTED SUMS, Science in China. Series A, Mathematics, Physics, Astronomy & Technological Sciences, 41(9), 1998, pp. 939-949
For a very general weight function, the equivalent renditions of compl
ete convergence for weighted sums of independent but not necessary ide
ntically distributed random variables are given. The previous situatio
n of only sufficient results except for particular weight functions is
changed. These results may help deduce many known ones and bring to l
ight richer content.
