题目：On virtual chirality of 3-manifolds

报告人：孙宏斌教授    Rutgers University

摘要：We prove that if a prime 3-manifold M is not finitely covered by the 3-sphere or a product manifold, then M is virtually chiral, i.e. it has a finite cover that does not admit an orientation reversing self-homeomorphism. For a general 3-manifold, it is virtually chiral if it has a virtually chiral prime summand. This is joint work with Zhongzi Wang.
