Petal grid diagrams of torus knots
Eon-Kyung Lee, Sang-Jin Lee
A petal diagram of a knot is a projection with a single multi-crossing such that there are no nested loops. The petal number of a knot is the minimum number of loops amo…
An upper bound of the minimal asymptotic translation length of right-angled Artin groups on extension graphs
Eon-Kyung Lee, Sang-Jin Lee
For the right-angled Artin group action on the extension graph, it is known that the minimal asymptotic translation length is bounded above by 2 provided that the defining graph ha…
Barcode entropy for Reeb flows on contact manifolds with Liouville fillings
Elijah Fender, Sangjin Lee, Beomjun Sohn
We study the topological entropy of Reeb flows on contact manifolds with Liouville fillings. With the theory of persistence modules, we define SH-barcode entropy from the symplecti…
Acylindricity of the action of right-angled Artin groups on extension graphs
Eon-Kyung Lee, Sang-Jin Lee
The action of a right-angled Artin group on its extension graph is known to be acylindrical because the cardinality of the so-called -quasi-stabilizer of a pair of distant point…
A comparison of categorical and topological entropies on Weinstein manifolds
Hanwool Bae, Sangjin Lee
Let be a symplectic manifold, and let be a symplectic automorphism. Then, induces an auto-equivalence defined on the Fukaya category of . In this paper,…
Uniqueness of quasi-roots in right-angled Artin Groups
Eon-Kyung Lee, Sang-Jin Lee
We introduce the notion of quasi-roots and study their uniqueness in right-angled Artin groups.
