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 30 September 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 January 2028.

Abstract

A semiring is an algebraic structure that satisfies the same axioms as a ring, except that subtraction is not required. Although this idea may have seemed unusual when first introduced by Vandiver in 1934, many familiar examples exist, such as the natural numbers and the nonnegative real numbers. Semirings have since become central in areas of theoretical computer science, including automata theory and optimization,…
