Flexible exponent of geometric 3-manifolds and Legendrian maps of Seifert spaces
Jianru Duan, Jianfeng Lin, Shicheng Wang +2
A classical question in quantitative topology is to bound the mapping degree in terms of its Lipchitz constant . For a closed, orient…
Maps between circle bundles: Fiber-preserving, Finiteness and Realization of mapping degree sets
Christoforos Neofytidis, Hongbin Sun, Ye Tian +2
Let be an oriented circle bundle over a closed oriented -manifold with and assume that is aspherical. We prove the following geometric realization resu…
Embedding periodic maps of surfaces into those of spheres with minimal dimensions
Chao Wang, Shicheng Wang, Zhongzi Wang
It is known that any periodic map of order on a closed oriented surface of genus can be equivariantly embedded into for some . In the orientable and smooth categor…
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…
