### Abstract

The $$R$$ R -boundedness of certain families of vector-valued stochastic convolution operators with scalar-valued square integrable kernels is the key ingredient in the recent proof of stochastic maximal $$L^p$$ L p -regularity, $$2<p<\infty$$ 2 < p < ∞ , for certain classes of sectorial operators acting on spaces $$X=L^q(\mu )$$ X = L q ( μ ) , $$2\le q<\infty$$ 2 ≤ q < ∞ . This paper presents a systematic study of $$R$$ R -boundedness of such families. Our main result generalises the afore-mentioned $$R$$ R -boundedness result to a larger class of Banach lattices $$X$$ X and relates it to the $$\ell ^{1}$$ ℓ 1 -boundedness of an associated class of deterministic convolution operators. We also establish an intimate relationship between the $$\ell ^{1}$$ ℓ 1 -boundedness of these operators and the boundedness of the $$X$$ X -valued maximal function. This analysis leads, quite surprisingly, to an example showing that $$R$$ R -boundedness of stochastic convolution operators fails in certain UMD Banach lattices with type $$2$$ 2 .
