地  点：晨兴中心510室

摘  要：I will talk about some results of Professor Sun Hongbin for the following question in which I am involved. When there are maps between closed orientable 3-manifolds and closed orientable 4-manifolds which induce isomorphisms on their fundamental groups? Some higher dimensional cases are also discussed.
