报告摘要：We mainly study the analytical properties of the Cartesian currents carried by graphs of some specific set-valued maps, including structure properties, weak continuity and approximability. Then we apply these results to study the Hessian measure, weak Jacobian and distributional determinant. Moreover，we obtain the weak continuous results and optimal results of distributional k-Hessian in the framework of Besov space.
