Random unconditional convergence of vector-valued Dirichlet series

Abstract

We study random unconditionality of Dirichlet series in vector-valued Hardy spaces Hp(X)\mathcal H_p(X). It is shown that a Banach space XX has type 2 (respectively, cotype 2) if and only if for every choice (xn)nX(x_n)_n\subset X it follows that (xnns)n(x_n n^{-s})_n is Random unconditionally convergent (respectively, divergent) in H2(X)\mathcal H_2(X). The analogous question on Hp(X)\mathcal H_p(X) spaces for p2p\neq2 is also explored. We also provide explicit examples exhibiting the differences between the unconditionality of (xnns)n(x_n n^{-s})_n in Hp(X)\mathcal H_p(X) and that of (xnzn)n(x_n z^n)_n in Hp(X)H_p(X).
