Title: Strong law of larg numbers for variables with infinite moments..
Let S_n be partial sums of i.i.d. variables from X.
Suppose E(X)=0 whenever E(|X|) is finite. For 0 < p < 2, the
Marcinkiewicz-Zygmund strong law of large numbers (SLLN)
asserts that E(|X|^p) is finite iff S_n n^{-1/p} converges to zero
almost surely. If E(|X|^p) is infinite, what is the almost sure
upper limit of S_n n^{-1/p} ?
