Random series in $L^p(X,\Sigma ,\mu )$ using unconditional basic sequences and $l^p$ stable sequences: A result on almost sure almost everywhere convergence

Abstract:

Here we study the almost sure almost everywhere convergence of random series of the form $\sum _{i=1}^{\infty } {a_i f_i}$ in the Lebesgue spaces $L^p(X,\Sigma ,\mu )$, where the $a_i$’s are centered random variables, and the $f_i$’s constitute an unconditional basic sequence or an $l^p$ stable sequence. We show that if one of these series converges in the norm topology almost surely, then it converges almost everywhere almost surely.
