Let convergences λi : B → P (B), i ≤ 4, on a complete Boolean algebra B be defined in the following way. For a sequence x = 〈xn : n ∈ ω〉 in B and the corresponding B-name for a subset of ω, τx = {〈ň, xn〉 : n ∈ ω}, let λi(x) = { {‖τx is infinite‖} if bi(x) = 1B, ∅ otherwise, where b1(x) = ‖τx is finite or cofinite‖, b2(x) = ‖τx is not unsupported‖, b3(x) = ‖τx is not a splitting real‖ and b4(x) ...

Let {Yi;-oc < i < c~} be a doubly infinite sequence of identically distributed and (b-mixing random variables, (ai; ~ < i < oc} an absolutely summable sequence of real numbers. In this paper, we prove the complete convergence of {Ek=xn ~io~=_¢xz ai+kYi/nt/,; n>~ 1} under some suitable conditions. AMS classification: 60G50; 60F15

for all x, y ∈ R. Moreover, it follows that 1.2 implies 1.1 , and hence, 1.1 and 1.2 are equivalent. Ebrahimi and Ghosh 1 showed that 1.1 and 1.2 are not equivalent for a collection of 3 or more random variables. They considered random variables X1, X2, and X3 where X1, X2, X3 assumed the values 0, 1, 1 , 1, 0, 1 , 1, 1, 0 , and 0, 0, 0 each with probability 1/4. The random variables X1, X2, an...
