Summary

Although the Borel conjecture is a uniqueness question, it has implications for problems of whether certain manifolds exist. We shall discuss a conjecture of Wall, and some of its evidence. And also within transformation groups, the Nielsen problem and an analogue of Connes and Raymond. Further afield, we discuss manifolds with excessive symmetry.
