Nonsingular structural stable chaotic 3-flows of attractor-repeller type
Zhentao Lai, V. Medvedev, Bin Yu +1
We show that any orientable closed 3-manifold admits structurally stable non-singular flow whose non-wandering set consists of a 2-dimensional expanding attract…

Note on Euler class 0 taut foliation on the Whitehead link exterior
Yao Fan, Zhentao Lai, Bin Yu
This paper studies the existence of co-orientable taut foliations on 3-manifolds, particularly focusing on the Whitehead link exterior. We demonstrate fundamental obstructions to t…
