First and second order optimality conditions for the control of Fokker-Planck equations

Abstract

In this article we study an optimal control problem subject to the Fokker-Planck equation∂tρ−ν∆ρ− div(ρB[u]) = 0The control variableuis time-dependent and possibly multidimensional, and the functionBdepends on the space variable and the control. The cost functional is of tracking type and includes a quadratic regularization term on the control. For this problem, we prove existence of optimal controls and first order necessary conditions. Main emphasis is placed on second order necessary and sufficient conditions.
