Defective coloring is perfect for minors
Chun-Hung Liu
The defective chromatic number of a graph class is the infimum such that there exists an integer such that every graph in this class can be partitioned into at most ind…
Spatio-Temporal Federated Learning for Massive Wireless Edge Networks
Chun-Hung Liu, Kai-Ten Feng, Lu Wei +1
This paper presents a novel approach to conduct highly efficient federated learning (FL) over a massive wireless edge network, where an edge server and numerous mobile devices (cli…
Toward Ubiquitous and Flexible Coverage of UAV-IRS-Assisted NOMA Networks
Chun-Hung Liu, Md Asif Syed, Lu Wei
This paper studies how to achieve a high and flexible coverage performance of a large-scale cellular network that enables unmanned aerial vehicles (UAVs) for non-orthogonal multipl…
Homomorphism counts in robustly sparse graphs
Chun-Hung Liu
For a fixed graph and for arbitrarily large host graphs , the number of homomorphisms from to and the number of subgraphs isomorphic to contained in have bee…
A 3D Modeling Approach to Tractable Analysis in UAV-Enabled Cellular Networks
Chun-Hung Liu, Di-Chun Liang, Rung-Hung Gau
This paper aims to propose a three-dimensional (3D) point process that can be employed to generally deploy unmanned aerial vehicles (UAVs) in a large-scale cellular network and tra…
Asymptotic Dimension of Minor-Closed Families and Assouad-Nagata Dimension of Surfaces
Marthe Bonamy, Nicolas Bousquet, Louis Esperet +4
The asymptotic dimension is an invariant of metric spaces introduced by Gromov in the context of geometric group theory. In this paper, we study the asymptotic dimension of metric…
