On distinct finite covers of 3-manifolds
Stefan Friedl, JungHwan Park, Bram Petri +2
Every closed orientable surface S has the following property: any two connected covers of S of the same degree are homeomorphic (as spaces). In this, paper we give a complete class…
Linear independence of cables in the knot concordance group
Christopher W. Davis, JungHwan Park, Arunima Ray
We produce infinite families of knots for which the set of cables is linearly independent in the knot concordance group. We arrange…
Pretzel links, mutation, and the slice-ribbon conjecture
Paolo Aceto, Min Hoon Kim, JungHwan Park +1
Let p and q be distinct integers greater than one. We show that the 2-component pretzel link P(p,q,-p,-q) is not slice, even though it has a ribbon mutant, by using 3-fold branched…
Multiple addition, deletion and restriction theorems for hyperplane arrangements
Takuro Abe, Hiroaki Terao
In the study of free arrangements, the most useful result to construct/check free arrangements is the addition-deletion theorem. Recently, the multiple version of the addition theo…
