An upper bound on the fractional chromatic number of triangle-free subcubic graphs
Chun-Hung Liu
An -coloring of a graph is a function which maps the vertices of into -element subsets of some set of size in such a way that is disjoint from $f(v…
Downlink Coordinated Multi-Point with Overhead Modeling in Heterogeneous Cellular Networks
Ping Xia, Chun-Hung Liu, Jeffrey G. Andrews
Coordinated multi-point (CoMP) communication is attractive for heterogeneous cellular networks (HCNs) for interference reduction. However, previous approaches to CoMP face two majo…
Linear colorings of subcubic graphs
Chun-Hung Liu, Gexin Yu
A linear coloring of a graph is a proper coloring of the vertices of the graph so that each pair of color classes induce a union of disjoint paths. In this paper, we prove that for…
A new bound for the 2/3 conjecture
Daniel Král', Chun-Hung Liu, Jean-Sébastien Sereni +2
We show that any n-vertex complete graph with edges colored with three colors contains a set of at most four vertices such that the number of the neighbors of these vertices in one…
