Abstract:We investigate characteristics of the Hamilton-Jacobi-Bellman
equation arising in nonlinear optimal control and their relationship with weak and strong local minima. This leads to an extension of the Jacobi conjugate points theory to the Bolza control problem. Necessary and sufficient optimality conditions for weak and strong local minima are stated in terms of the existence of a solution to a corresponding matrix Riccati differential equation.

Keywords:Hamilton-Jacobi-Bellman equation  characteristics  conjugate point  necessary and sufficient conditions for optimality  Riccati differential equation  shock  value function  weak local minimum
