Abstract
Consider the discrete cubic Hilbert transform defined on finitely supported functions on by
We prove that there exists and universal constant such that for all finitely supported on there exists an -sparse form for which
This is the first result of this type concerning discrete harmonic analytic operators. It immediately implies some weighted inequalities, which are also new in this setting.
