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 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2027.

Abstract

Our universe (space-time) has an underlying mathematical structure called a four-dimensional manifold, and yet surprisingly, we understand very little about the geometry of four-dimensional spaces. Topology studies the fundamental properties of space that remain unchanged even when the structure is continuously bent and deformed, while dynamics studies the self-mappings of the space that preserve a given structure.…
