Multitime Optimal Control in Resource Economics Constantin Udriste1; 1UNIVERSITY POLITEHNICA OF BUCHAREST, Bucharest, Romania; PAPER: 191/Mathematics/Invited (Oral) SCHEDULED: 16:20/Tue./Grego (50/3rd) ABSTRACT: Multitime optimal control theory has been recently used in economics. Here, we develop some ideas using the context of optimal control and differential geometry. Specifically, two problems are analysed: (i) multitime evolution of reproducible resources, and (ii) multitime evolution of non-reproducible resources. The technique is to associate each problem with proper functional (like multiple integral or curvilinear integral) and appropriate constraints (geometric PDEs like m-flows, Goursat-Darboux PDEs, parallelism PDEs, and specific isoperimetric constraints like integrals). When the Hamiltonian is linear affine in the control, we focus on bang-bang and singular optimal controls. References: [1] C. Udriste, M.
