Double domination in lexicographic product graphs [PDF]

open access: yes, 2020
[EN] In a graph G, a vertex dominates itself and its neighbours. A subset S subset of V(G) is said to be a double dominating set of G if S dominates every vertex of G at least twice.

Bias‐Triggered Conductivity Relaxation (BCR): A Unique Tool to Simultaneously Investigate Thermodynamics, Kinetics, and Electrostatic Effects of Oxygen Reactions in MIEC Thin Films

open access: yesAdvanced Materials, Volume 38, Issue 43, 3 August 2026.
This work develops bias‐triggered conductivity relaxation as a novel technique to study oxygen reactions in mixed ionic‐electronic conducting thin films by integrating electrochemical titration and electrical conductivity relaxation to achieve synchronous multi‐parameter characterization, providing simultaneous electronic, ionic, and extraordinarily ...

Double Roman domination in generalized Petersen graphs P(ck, k)

open access: yes, 2022
A double Roman dominating function on a graph G=(V,E) is a function f:V→{0,1,2,3}, satisfying the condition that every vertex u for which f(u)=1 is adjacent to at least one vertex assigned 2 or 3, and every vertex u with f(u)=0 is adjacent to at ...

Further Results on the Total Roman Domination in Graphs [PDF]

open access: yes, 2020
[EN] Let G be a graph without isolated vertices. A function f:V(G)-> {0,1,2} is a total Roman dominating function on G if every vertex v is an element of V(G) for which f(v)=0 is adjacent to at least one vertex u is an element of V(G) such that f(u)=

Total Roman domination for proper interval graphs

open access: yes, 2020
A function f:V → {0,1,2} is a total Roman dominating function (TRDF) on a graph G=(V,E) if for every vertex v ∈ V with f(v) = 0 there is a vertex u adjacent to v with f(u) = 2 and for every vertex v ∈ V with f(v) > 0 there exists a vertex u ∈ NG(v ...

On The Total Roman Domination in Trees [PDF]

open access: yes, 2019
A total Roman dominating function on a graph G is a function f : V (G) → {0, 1, 2} satisfying the following conditions: (i) every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f(v) = 2 and (ii) the subgraph of G induced by ...

The restrained double Roman domination and graph operations

open access: yes
A restrained double Roman dominating function (RDRD-function) on a graph G is a function f:V(G)→{0, 1, 2, 3} that satisfies two conditions: (1) If f(v)

Upper bounds for double Roman domination and $[k]$-Roman domination of cylindrical graphs $C_mBox P_n$ [PDF]

open access: yes
Roman-type domination parameters form an important class of graph invariants that model protection and resource allocation problems on networks. Among them, $[k]$-Roman domination provides a unified framework that generalizes Roman, double Roman, and ...
