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 October 2026.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 February 2027.

Abstract

Symplectic geometry shares deep connections with many other fields of mathematics such as complex geometry, smooth topology, algebraic geometry, and dynamics. However, we still do not have a good understanding of what a symplectic manifold should look like. Early work on understanding the topology of symplectic manifolds dates back to the groundbreaking work of Gromov in the 1980s, with the invention of…
