Abstract

Consider the discrete quadratic phase Hilbert Transform acting on 2\ell^{2} finitely supported functions Hαf(n):=m0e2πiαm2f(nm)m. H^{\alpha} f(n) : = \sum_{m \neq 0} \frac{e^{2 \pi i\alpha m^2} f(n - m)}{m}. We prove that, uniformly in αT\alpha \in \mathbb{T}, there is a sparse bound for the bilinear form Hαf,g\langle H^{\alpha} f , g \rangle. The sparse bound implies several mapping properties such as weighted inequalities in an intersection of Muckenhoupt and reverse H\"older classes.
