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 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

The goal of this award is to further the understanding of dynamical systems and geometry relating to important families of surfaces. Dynamical systems (systems that evolve over time) are ubiquitous mathematical objects that can be used to model real world phenomena such as weather systems, robotics, and the motion of particles. Surfaces are two-dimensional structures that play a fundamental role in mathematics, as…
