Characterization of All Graphs with a Failed Skew Zero Forcing Number of 1

Mathematics, 2022
Given a graph G, the zero forcing number of G, Z(G), is the minimum cardinality of any set S of vertices of which repeated applications of the forcing rule results in all vertices being in S.

GRAPHS WITH TOTAL FORCING NUMBER TWO, REVISITED [PDF]

Journal of Algebraic Systems, 2021
A subset of the vertex set of a graph $G$ is called a zero forcing set if by considering them colored and, as far as possible, a colored vertex with exactly one non-colored neighbor forces its non-colored neighbor to get colored, then the whole vertices ...

Connected zero forcing sets and connected propagation time of graphs [PDF]

Transactions on Combinatorics, 2020
The zero forcing number $Z(G)$ of a graph $G$ is the minimum cardinality of a set $S$ with colored (black) vertices which forces the set $V(G)$ to be colored (black) after some times.

Fuzzy Forcing Set on Fuzzy Graphs [PDF]

Journal of Mahani Mathematical Research, 2019
The investigation of impact of fuzzy sets on zero forcing set is the main aim of this paper. According to this, results lead us to a new concept which we introduce it as Fuzzy Zero Forcing Set (FZFS). We propose this concept and suggest a polynomial time

An Inverse Approach for Finding Graphs with a Failed Zero Forcing Number of k

Mathematics, 2023
For a given a graph G, the zero forcing number of G, Z(G), is the smallest cardinality of any set S of vertices on which repeated applications of the forcing rule results in all vertices being included in S.

Impact of negative and positive CO₂ emissions on global warming metrics using an ensemble of Earth system model simulations [PDF]

Biogeosciences, 2022
The benefits of implementing negative emission technologies in the global warming response to cumulative carbon emissions until the year 2420 are assessed following the shared socioeconomic pathway (SSP) 1-2.6, the sustainable development scenario, with ...

GCI Fusion-Based Anti-Deception Jamming Algorithm for Distributed Radar [PDF]

Hangkong bingqi, 2022
Aiming at the anti-jamming problem of distributed radar against multiple false targets, an anti-jamming algorithm based on data level fusion is proposed. Firstly, the cardinalized probability hypothesis density (CPHD) filter based on random finite set is
