We provebounds for the extensions of standard multilinear Calderón–Zygmund operators to tuples ofspaces tied by a natural product structure. The product can, for instance, mean the pointwise product infunction lattices, or the composition of operators in the Schatten-von Neumann subclass of the algebra of bounded operators on a Hilbert space. We do not require additional assumptions beyondon each space—in contrast to previous results, we e.g. show that the Rademacher maximal function property is not necessary. The obtained generality allows for novel applications. For instance, we prove new versions of fractional Leibniz rules via our results concerning the boundedness of multilinear singular integrals in non-commutativespaces. Our proof techniques combine a novel scheme of induction on the multilinearity index with dyadic-probabilistic techniques in thespace setting.
