چکیده

Lattices have been used in several problems in coding theory and cryptography. In this paper we approach q-ary lattices obtained via Constructions D, D′ and D. It is shown connections between Constructions D and D′. Bounds for the minimum l1-distance of lattices ΛD, ΛD′ and ΛD and, under certain conditions, a generator matrix for ΛD′ are presented. In addition, when the chain of codes used is closed under the zero-one addition, we derive explicit expressions for the minimum l1-distances of the lattices ΛD and ΛD attached to the distances of the codes used in these constructions.

Lattices from codes over $\mathbb{Z}_n$: Generalization of Constructions $D$, $D'$ and $\overline{D}$

In this paper, we extend the lattice Constructions D, D′ and D (this latter is also known as Forney’s code formula) from codes over Fp to linear codes over Zq, where q ∈ N. We define an operation in Zq called zero-one addition, which coincides with the Schur product when restricted to Z2 and show that the extended Construction D produces a lattice if and only if the nested codes are closed unde...

Some results on the energy of the minimum dominating distance signless Laplacian matrix assigned to graphs

Let G be a simple connected graph. The transmission of any vertex v of a graph G is defined as the sum of distances of a vertex v from all other vertices in a graph G. Then the distance signless Laplacian matrix of G is defined as D^{Q}(G)=D(G)+Tr(G), where D(G) denotes the distance matrix of graphs and Tr(G) is the diagonal matrix of vertex transmissions of G. For a given minimum dominating se...

The Steiner diameter of a graph

‎The Steiner distance of a graph‎, ‎introduced by Chartrand‎, ‎Oellermann‎, ‎Tian and Zou in 1989‎, ‎is a natural generalization of the‎ ‎concept of classical graph distance‎. ‎For a connected graph $G$ of‎ ‎order at least $2$ and $Ssubseteq V(G)$‎, ‎the Steiner‎ ‎distance $d(S)$ among the vertices of $S$ is the minimum size among‎ ‎all connected subgraphs whose vertex sets contain $S$‎. ‎Let $...

On the super domination number of graphs

The open neighborhood of a vertex $v$ of a graph $G$ is the set $N(v)$ consisting of all vertices adjacent to $v$ in $G$. For $Dsubseteq V(G)$, we define $overline{D}=V(G)setminus D$. A set $Dsubseteq V(G)$ is called a super dominating set of $G$ if for every vertex $uin overline{D}$, there exists $vin D$ such that $N(v)cap overline{D}={u}$. The super domination number of $G$ is the minimum car...

D-Spectrum and D-Energy of Complements of Iterated Line Graphs of Regular Graphs

The D-eigenvalues {µ1,…,µp} of a graph G are the eigenvalues of its distance matrix D and form its D-spectrum. The D-energy, ED(G) of G is given by ED (G) =∑i=1p |µi|. Two non cospectral graphs with respect to D are said to be D-equi energetic if they have the same D-energy. In this paper we show that if G is an r-regular graph on p vertices with 2r ≤ p - 1, then the complements of iterated lin...
