Bisected vertex leveling of plane graphs: braid index, arc index and delta diagrams

Sungjong No, Seungsang Oh, Hyungkee Yoo

In this paper, we introduce a bisected vertex leveling of a plane graph. Using this planar embedding, we present elementary proofs of the well-known upper bounds in terms of the mi…

Stick number of spatial graphs

Minjung Lee, Sungjong No, Seungsang Oh

For a nontrivial knot $K$ , Negami found an upper bound on the stick number $s (K)$ in terms of its crossing number $c (K)$ which is $s (K) \leq 2 c (K)$ . Later, Huh and Oh utilized the…

Circuit presentation and lattice stick number with exactly 4 $z$ -sticks

Hyoungjun Kim, Sungjong No

The lattice stick number $s_{L} (L)$ of a link $L$ is defined to be the minimal number of straight line segments required to construct a stick presentation of $L$ in the cubic lattice…
