We have yet to see any rebound in middle school math on the nation’s report card, where scores declined by 8 points from 2019 to 2022 and remained at that low point when kids last took NAEP in 2024.
Abstract: An iterative algorithm to solve periodic Riccati differential equations (PRDE) with an indefinite quadratic term is proposed. In our algorithm, we replace the problem of solving a PRDE with ...

Mathematicians finally understand the behavior of an important class of differential equations that describe everything from water pressure to oxygen levels in human tissues. The trajectory of a storm ...
Abstract: This paper studies a linear-quadratic optimal control problem derived by forward-backward stochastic differential equations, where the drift coefficient of ...
