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

"High-dimensional expanders" (HDXs) are special kinds of mathematical networks that allow a large number of points to be interconnected very efficiently. Recently, a few methods for creating them have been discovered, and these discoveries have led to breakthrough advances in areas such as error-correcting codes, data-routing algorithms, and quantum computing. Unfortunately, we still know very few methods for…
