Laplacian eigenvalue distribution for unicyclic graphs
Sunyo Moon, Seungkook Park
Let be a unicyclic graph. In this paper, we provide an upper bound for the number of Laplacian eigenvalues of within the interval in terms of the diameter and the g…
Bounds for the geometric-arithmetic index of unicyclic graphs
Sunyo Moon, Seungkook Park
We present lower and upper bounds for the geometric-arithmetic index of unicyclic graphs and provide extremal graphs for the corresponding bounds.
The rank of the walk matrix of the extended Dynkin graph
Sunyo Moon, Seungkook Park
In this paper, we provide an explicit formula for the rank of the walk matrix of the extended Dynkin graph .
Classification of graphs by Laplacian eigenvalue distribution and independence number
Jinwon Choi, Sunyo Moon, Seungkook Park
Let denote the number of Laplacian eigenvalues of a graph in an interval and let denote the independence number of . In this paper, we determine the classe…
Distance bounds for algebraic geometric codes
Iwan Duursma, Radoslav Kirov, Seungkook Park
Various methods have been used to obtain improvements of the Goppa lower bound for the minimum distance of an algebraic geometric code. The main methods divide into two categories…
Minimum distance of Hermitian two-point codes
Seungkook Park
We prove a formula for the minimum distance of two-point codes on a Hermitian curve.
