Hamilton-Jacobi-Bellman equation and viscosity solutions for the optimal control problem of stochastic convective Brinkman-Forchheimer equations

This work is devoted to the infinite-dimensional second-order Hamilton-Jacobi-Bellman equation associated, via the dynamic programming approach, with an optimal control problem for the two- and three-dimensional stochastic convective Brinkman-Forchheimer equations on the torus, d...

Ensemble agroecosystem modeling enhances predictions of crop yields and soil carbon across the United States

Abstract. Accurately estimating crop yields and soil organic carbon (SOC) dynamics is essential for agricultural planning, carbon accounting, and sustainable land management. However, process-based agroecosystem models often produce divergent estimates due to variations in model...
