Left orderability and taut foliations with orderable cataclysm
Bojun Zhao
Let be a connected, closed, orientable, irreducible -manifold. We show that: if admits a co-orientable taut foliation with orderable cataclysm, then $π_1(M…
Left orderability and taut foliations with one-sided branching
Bojun Zhao
For a closed orientable irreducible -manifold that admits a co-orientable taut foliation with one-sided branching, we show that is left orderable.
Left orderability, foliations, and transverse structures for -manifolds with sphere boundary
Bojun Zhao
Let be a closed orientable irreducible -manifold such that is left orderable. (a) Let , where is a compact -ball in . We have a…
Extensions of immersions of surfaces into
Bojun Zhao
This paper is to study the case of \hyperref[Zhao]{[9]}. We determine all equivalence classes of immersed -manifolds bounded by an arbitrary immersed surface in…
The extending surfaces of immersions into surfaces
Bojun Zhao
S. Blank solved the question of classifying immersed circles in that extend to immersed disks, and how many topologically inequivalent disks can be extended. The q…
