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 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2028.

Abstract

This project investigates the mathematics of dynamical systems defined by repeatedly applying algebraic rules. Such systems arise throughout science and technology, where complex behavior emerges from simple iterative processes. A central challenge is to understand when a dynamical system exhibits hidden structure rather than generic chaotic behavior. The project studies special geometric configurations that govern…
