    We provide a simple criterion on a family of functions that implies a square function estimate on L p L^p for every even integer p ≥<#comment/> 2 p \geq 2 . This defines a new type of superorthogonality that is verified by checking a less restrictive criterion than any other type of superorthogonality that is currently known.

    Abstract We prove almost everywhere convergence of continuous-time quadratic averages with respect to two commuting $$\mathbb {R}$$ -actions, coming from a single jointly measurable measure-preserving $$\mathbb {R}^2$$ -action on a probability space. The key ingredient of the proof comes from recent work on multilinear singular integrals; more specifically, from the study of a curved model for the triangular Hilbert transform.
