Boundary curves of surfaces with the 4-plane property
Tao Li
Let M be an orientable and irreducible 3-manifold whose boundary is an incompressible torus. Suppose that M does not contain any closed nonperipheral embedded incompressible surfac…
An algorithm to find vertical tori in small Seifert fiber spaces
Tao Li
We give an algorithm to find vertical essential tori in small Seifert fiber spaces with infinite fundamental groups. This implies that there are algorithms to decide whether a 3-ma…
Laminar Branched Surfaces in 3-manifolds
Tao Li
We define a laminar branched surface to be a branched surface satisfying the following conditions: (1) Its horizontal boundary is incompressible; (2) there is no monogon; (3) there…
An algorithm to detect laminar 3-manifolds
Ian Agol, Tao Li
We show that there are algorithms to determine if a 3-manifold contains an essential lamination or a Reebless foliation.
