Title: Optimal control for sweeping processes to prox-regular sets with free-time Trang Nguyen Abstract: This talk concerns the optimal control of discontinuous differential inclusions of the normal cone type governed by a generalized version of the Moreau sweeping process with free-time and the control functions acting in nonconvex moving sets, perturbations, and running cost. This is a new class of optimal control problems to prox-regular sets with free-time in comparison with previously considered counterparts where the controlled sweeping sets are described by convex polyhedra and fixed time.   Based on a constructive discrete approximation approach and advanced tools of first-order and second-order variational analysis and generalized differentiation, we establish the strong convergence of discrete optimal solutions and derive a complete set of necessary optimality conditions for discrete-time and continuous-time sweeping control systems that are expressed entirely via the problem data.
