Reconfiguration graphs of zero forcing sets

open access: yesDiscrete Applied Mathematics, 2023
This paper begins the study of reconfiguration of zero forcing sets, and more specifically, the zero forcing graph. Given a base graph $G$, its zero forcing graph, $\mathscr{Z}(G)$, is the graph whose vertices are the minimum zero forcing sets of $G$ with an edge between vertices $B$ and $B'$ of $\mathscr{Z}(G)$ if and only if $B$ can be obtained from $

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

open access: yesTransactions 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.

The Bipartite Zero Forcing Set for a Full Sign Pattern Matrix [PDF]

open access: yesMathematics, 2020
For an m × n sign pattern P, we define a signed bipartite graph B ( U , V ) with one set of vertices U = { 1 , 2 , … , m } based on rows of P and the other set of vertices V = { 1 ′ , 2 ′ , … ,

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

open access: yesMathematics, 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]

open access: yesJournal 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 ...

Signed zero forcing number and controllability for a networks system with a directed hypercube [PDF]

open access: yesMATEC Web of Conferences, 2022

Fuzzy Forcing Set on Fuzzy Graphs [PDF]

open access: yesJournal 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

open access: yesMathematics, 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]

open access: yesBiogeosciences, 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 ...
