We prove that the value function is the unique bounded viscosity solution on the closed simplex of the Hamilton\u2013Jacobi\u2013Bellman equation by a direct dynamic-programming argument and a finite-state comparison principle. Under a uniform semiconvexity condition and C\u00b9,\u00b9 regularity, the value function is globally semiconvex and intrinsically C\u00b9,\u00b9 on the closed simplex and yields a Gibbs feedback that is the unique Hamiltonian minimizer at interior states. For positive, symmetric, possibly state-dependent reference rates, an entropy-plus-value free energy decays globally exponentially when the temperature parameter is compatible with the semiconvexity modulus. We also establish a discounted planner-to-game correspondence for potential mean field games under a state-independent reference generator.", "occurrence_notes":null, "guid":"153194-21915402@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/153194", "building_id":"1", "building_name":"Angell Hall", "campus_maps_id":"12", "room":"AHG128", "location_name":"Angell Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Financial\/Actuarial Mathematics Seminar - Department of Mathematics", "group_id":"4890", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21915402 } }
