报告题目/Title：Prescribing the volume form and the Jacobian determinant equation

摘要/Abstract：I will talk about the problem to prescribe the Jacobian determinant or the volume form, present some classical and more recent results on this problem. I will mention also the understanding of the Jacobian determinant for homeomorphisms in Sobolev spaces, and the associated density problem.
