Necessary and sufficient conditions of a class of bipartite graphs with local antimagic chromatic number 2 - an algebraic approach
Gee-Choon Lau, Wai Chee Shiu
For a connected graph , a bijective edge labeling is a local antimagic labeling of if it induces a vertex labeling such that for an…
A novel approach to determining chromatic number induced by labelings
Gee-Choon Lau, Wai Chee Shiu, Zhen Bin Gao
Given a simple graph of order and size , a bijection is a local total neighborhood antimagic labeling of if the induced…
On local antimagic chromatic number of the join of two special families of graphs -- II
Gee-Choon Lau, Wai Chee Shiu
It is known that null graphs and 1-regular graphs are the only regular graphs without local antimagic chromatic number. In this paper, we proved that the join of 1-regular graph an…
New Families of tripartite graphs with local antimagic chromatic number 3
Gee-Choon Lau, Wai Chee Shiu
For a graph of size , a bijection is a local antimagc labeling if it induces a vertex labeling such that $f^+(u) \ne f^…
On local antimagic chromatic numbers of the join of two special families of graphs
Gee-Choon Lau, Wai Chee Shiu
It is known that null graphs and 1-regular graphs are the only regular graphs without local antimagic chromatic number. In this paper, we use matrices of size $(2m+1) \times (2k+1)…
On local antimagic total chromatic number of certain one point union of graphs
Gee-Choon Lau
Let be a connected simple graph of order and size . A bijection is called a local antimagic total labeling of if for…
