The minor minimal intrinsically chiral graphs
Howon Choi, Hyoungjun Kim, Sungjong No
Molecular chirality is actively researched in a variety of areas of biology, including biochemistry, physiology, pharmacology, etc., and today many chiral compounds are widely know…
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 , Negami found an upper bound on the stick number in terms of its crossing number which is . Later, Huh and Oh utilized the…
Circuit presentation and lattice stick number with exactly 4 -sticks
Hyoungjun Kim, Sungjong No
The lattice stick number of a link is defined to be the minimal number of straight line segments required to construct a stick presentation of in the cubic lattice…
Arc index of spatial graphs
Minjung Lee, Sungjong No, Seungsang Oh
Bae and Park found an upper bound on the arc index of prime links in terms of the minimal crossing number. In this paper, we extend the definition of the arc presentation to spatia…
