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…
Coverage Analysis for Dense Heterogeneous Networks with Cooperative NOMA
Chun-Hung Liu, Di-Chun Liang, Po-Chia Chen +1
In a heterogeneous cellular network (HetNet) consisting of tiers of densely-deployed base stations (BSs), consider that each of the BSs in the HetNet that are associated with m…
Well-quasi-ordering digraphs with no long alternating paths by the strong immersion relation
Chun-Hung Liu, Irene Muzi
Nash-Williams' Strong Immersion Conjecture states that graphs are well-quasi-ordered by the strong immersion relation. That is, given infinitely many graphs, one graph contains ano…
A 3D Tractable Model for UAV-Enabled Cellular Networks With Multiple Antennas
Chun-Hung Liu, Di-Chun Liang, Md Asif Syed +1
This paper aims to propose a three-dimensional (3D) point process model that can be employed to generally deploy unmanned aerial vehicles (UAVs) in a large-scale cellular network a…
Asymptotic dimension of minor-closed families and beyond
Chun-Hung Liu
The asymptotic dimension of metric spaces is an important notion in geometric group theory introduced by Gromov. The metric spaces considered in this paper are the ones whose under…
Immersion and clustered coloring
Chun-Hung Liu
Hadwiger and Hajós conjectured that for every positive integer , -minor free graphs and -topological minor free graphs are properly -colorable, respectively…
