Maps between circle bundles: Fiber-preserving, Finiteness and Realization of mapping degree sets

Christoforos Neofytidis, Hongbin Sun, Ye Tian +2

Let $E_{i}$ be an oriented circle bundle over a closed oriented aspherical $n$ -manifold $M_{i}$ with Euler class $e_{i} \in H^{2} (M_{i}; Z)$ , $i = 1, 2$ . We prove the following: (i) If e…

Achirality of Sol 3-Manifolds, Stevenhagen Conjecture and Shimizu's L-series

Ye Tian, Shicheng Wang, Zhongzi Wang

A closed orientable manifold is {\em achiral} if it admits an orientation reversing homeomorphism. A commensurable class of closed manifolds is achiral if it contains an achiral el…
