A remark on the counterexample to the unknotting number conjecture
Chao Wang, Yimu Zhang
By using Snappy, M. Brittenham and S. Hermiller discovered a very surprising example that , where is the -toru…
Bordered surfaces in the 3-sphere with maximum symmetry
Chao Wang, Shicheng Wang, Yimu Zhang +1
We consider orientation-preserving actions of finite groups on pairs , where denotes a compact connected surface embedded in . In a previous paper, we consid…
Embedding compact surfaces into the 3-dimensional Euclidean space with maximum symmetry
Chao Wang, Shicheng Wang, Yimu Zhang +1
The symmetries of surfaces which can be embedded into the symmetries of the 3-dimensional Euclidean space are easier to feel by human's intuition. We give the maximu…
Graphs in the 3--sphere with maximum symmetry
Chao Wang, Shicheng Wang, Yimu Zhang +1
We consider the orientation-preserving actions of finite groups on pairs , where is a connected graph of genus , embedded in . For each we give the…
Alternating Heegaard diagrams and Williams solenoid attractors in 3--manifolds
Chao Wang, Yimu Zhang
We find all Heegaard diagrams with the property "alternating" or "weakly alternating" on a genus two orientable closed surface. Using these diagrams we give infinitely many genus t…
Maximum Orders of Cyclic and Abelian Extendable Actions on Surfaces
Chao Wang, Yimu Zhang
Let be a closed surface embedded in . If a group can acts on the pair , then we call such a group action on extendable over . In this pa…
