题目：Bordism of L^2-acyclic manifolds
报告人：Prof. J. Davis (Indiana University)
摘要:
A manifold is L^2-acyclic if its L^2-Betti numbers vanish. One can ask when an L^2-acyclic manifold is a boundary of an L^2-acyclic manifold with the same fundamental group.
We develop the geometric topology necessary to answer this question for manifolds of dimension greater than 4 and virtually abelian fundamental group.
This is joint work with Sylvain Cappell and Shmuel Weinberger.
