+  * **December 4th** \\ Speaker: **Hongbin Sun (Rutgers) ** \\ Title: ** On virtual chirality of 3-manifolds ** <WRAP box>// Abstract: // 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 non-prime 3-manifold, it is virtually chiral if it has a virtually chiral prime summand. This is joint work with Zhongzi Wang. \\ </WRAP>
