Isotopy Uniqueness of Self-diffeomorphism of Handlebodies
Fang Sun, Xuezhi Zhao
The mapping class group of a surface of genus has a long-history in topology and group theory. More recently, the mapping class group of a handlebody $V_g…
Local Coefficients Revisited
Slawomir Kwasik, Fang Sun
Two simple "simplicial approximation" tricks are invoked to prove basic results involving (co)-homology with local coefficients.
An elementary proof for Poincare Duality with local coefficients
Fang Sun
An proof of Poincare Duality with local coefficients and with compact support is provided. The proof does not require Sheaf Theory or anything equivalent and is thus more accessibl…
Topological Symmetries of R^3, II
Fang Sun
If a fintie group G acts topologically and faithfully on R^3, then G is a subgroup of O(3)
Topological Symmetries of R^3
Slawomir Kwasik, Fang Sun
If a finite group acts topologically, faithfully and orientation preservingly on R^3, then it is isomorphic to a subgroup of SO(3).
