The Semitotal Domination Problem in Block Graphs
A set D of vertices in a graph G is a dominating set of G if every vertex outside D is adjacent in G to some vertex in D. A set D of vertices in G is a semitotal dominating set of G if D is a dominating set of G and every vertex in D is within distance 2

How changing physical constants and violation of local position invariance may occur? [PDF]
Light scalar fields very naturally appear in modern cosmological models, affecting such parameters of Standard Model as electromagnetic fine structure constant $\alpha$, dimensionless ratios of electron or quark mass to the QCD scale, $m_{e,q}/\Lambda_ ...

Unique Minimum Semipaired Dominating Sets in Trees
Let G be a graph with vertex set V. A subset S ⊆ V is a semipaired dominating set of G if every vertex in V \ S is adjacent to a vertex in S and S can be partitioned into two element subsets such that the vertices in each subset are at most distance two ...

Distance d-Domination Games [PDF]
We study graph searching games where a number of cops try to capture a robber that is hiding in a system of tunnels modelled as a graph. While the current position of the robber is unknown to the cops, each cop can see a certain radius d around his position.

Zeroth-order general Randić index of trees with given distance k-domination number
The zeroth-order general Randić index of a graph G is defined as Ra(G)=∑v ∈ V(G)dGa(v), where a ∈ ℝ, V(G) is the vertex set of G and dG(v) is the degree of a vertex v in G.

The Numerical Invariants concerning the Total Domination for Generalized Petersen Graphs
A subset S of VG is called a total dominating set of a graph G if every vertex in VG is adjacent to a vertex in S. The total domination number of a graph G denoted by γtG is the minimum cardinality of a total dominating set in G.

Extremal values on Zagreb indices of trees with given distance k-domination number
Let G = ( V ( G ) , E ( G ) ) $G=(V(G),E(G))$ be a graph. A set D ⊆ V ( G ) $D\subseteq V(G)$ is a distance k-dominating set of G if for every vertex u ∈ V ( G ) ∖ D $u\in V(G)\setminus D$ , d G ( u , v ) ≤ k $d_{G}(u,v)\leq k$ for some vertex v ∈ D $v ...

Cosmology in a String-Dominated Universe [PDF]
The string-dominated universe locally resembles an open universe, and fits dynamical measures of power spectra, cluster abundances, redshift distortions, lensing constraints, luminosity and angular diameter distance relations and microwave background ...
