The Zero Forcing Number of Twisted Hypercubes
Twisted hypercubes are graphs that generalize the structure of the hypercube by relaxing the symmetry constraint while maintaining degree-regularity and connectivity. We study the zero forcing number of twisted hypercubes. Zero forcing is a graph infection process in which a particular colour change rule is iteratively applied to the graph and an ...

Some results on minimum skew zero forcing sets, and skew zero forcing number
, 2014 Let $G$ be a graph, and $Z$ a subset of its vertices, which we color black, while the remaining are colored white. We define the skew color change rule as follows: if $u$ is a vertex of $G$, and exactly one of its neighbors $v$, is white, then change the color of $v$ to black.

On the Performance of Multi-Way Massive MIMO Relay With Linear Processing
IEEE AccessPrevious works on multi-way massive MIMO relay only consider either Matched Filter (MF)/Maximum Ratio Transmission (MRT) or Zero Forcing as the pairs for the detector (or receiver) and the precoder for the uplink and downlink transmissions, respectively.

0047 | Zero Forcing Number in Neutrosophic Graphs
, 2022 New setting is introduced to study zero forcing number and zero forcing neutrosophic-number. Leaf-like is a key term to have these notions. Let NTG : (V,E,σ,μ) be a neutrosophic graph. Then zero forcing number Z(NTG) for a neutrosophic graph NTG : (V,E,σ,μ) is minimum cardinality of a set S of black vertices (whereas vertices in V (G) \ S are colored ...

Controllability and heterogeneity of river networks using spectral graph theory approach
Scientific ReportsRiver networks are important landscape features that have been extensively studied over many years. While seminal works have focused on characterizing the topological properties of river networks, the quantification of their spectral properties has ...

On the Number of Zero Forcing Minimal Forts on Trees
We solve a conjecture by Becker et al. (arXiv:2404.05963) on the topic of zero forcing regarding the number of minimal forts of a tree. They conjectured and we prove $\mathcal{F}_{T_n} \le \binom{n}{2} \mathcal{F}_{P_n}$ where $\mathcal{F}_{T_n}$ is the maximum number of minimal forts on a tree on $n$ vertices and $\mathcal{F}_{P_n}$ is the number of ...

Dianxin kexue, 2016 In the massive MIMO system, the only full digital baseband precoding（FD-BP）scheme（such as full complexity zero forcing）requires the same number of radio frequency（RF）chains as the number of antenna elements, which leads to extreme high hardware cost, the
