Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2029.

Abstract

This project in classical harmonic analysis studies multilinear operators with curvature and their connections with additive combinatorics and ergodic theory. Multilinear operators describe interactions among several functions, while curvature reflects the nonlinear geometric structure present in the underlying singular integrals, maximal operators, and oscillatory averages. Such problems are central in modern…
