Minimal Filling $K$ -Systems of Curves

Hong Chang, Xiao Chen, Wujie Shen

In this paper, we determine the exact minimal number of curves in a filling $k$ -system on an oriented surface of genus $g$ for any positive integers $k$ and $g$ .

A Linear Bound on the Diameter of the Kakimizu Complex for Hyperbolic Knots

Xiao Chen, Wujie Shen

This paper focuses on the Kakimizu complex of a hyperbolic knot $K$ . We define a complex $I S_{ℓ} (K)$ to study incompressible Seifert surfaces of genus at most $ℓ$ , and prove th…

Uniqueness of Maximal Curve Systems on Punctured Projective Planes

Xiao Chen, Wujie Shen

We show that the maximal $1$ -system of loops in a punctured projective plane is unique up to the mapping class group action if and only if the number of punctures is at most five.
