Timoshin", "Chen Bin" ], "categories": [ "math.AP", "math.OC" ], "abstract": "This paper addresses a nonlinear partial differential control system arising in population dynamics. The system consist of three diffusion equations describing the evolutions of three biological species: prey, predator, and food for the prey or vegetation. The equation for the food density incorporates a hysteresis operator of generalized stop type accounting for underlying hysteresis effects occurring in the dynamical process. We study the problem of minimization of a given integral cost functional over solutions of the above system. The set-valued mapping defining the control constraint is state-dependent and its values are nonconvex as is the cost integrand as a function of the control variable. Some relaxation-type results for the minimization problem are obtained and the existence of a nearly optimal solution is established.", "revisions": [ { "version": "v1", "updated": "2021-04-19T11:36:10.000Z" } ], "analyses": { "keywords": [ "population dynamics model", "optimal control", "hysteresis", "nonlinear partial differential control system", "partial differential control system arising" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
