Deforming abelian elliptic $SL (2, R)$ --representations of knot groups

Yi Liu

The following criterion is proved in this paper. If the Alexander polynomial of a knot $K \subset S^{3}$ has a zero of odd order on the complex unit circle, then there exists a contin…

A criterion for virtual Euler class one

Yi Liu

Let $M$ be an oriented closed hyperbolic $3$ --manifold. Suppose that $w$ is a rational second cohomology class of $M$ with dual Thurston norm $1$ . Upon the existence of certain non…

On the Euler class one conjecture for fillable contact structures

Yi Liu

In this paper, it is proved that every oriented closed hyperbolic $3$ --manifold $N$ admits some finite cover $M$ with the following property. There exists some even lattice point $…
