Bounding the rainbow domination number of a tree in terms of its annihilation number
(University of Isfahan, 2013-09-01)A $2$-rainbow dominating function (2RDF) of a graph $G$ is a function $f$ from the vertex set $V(G)$ to the set of all subsets of the set ${1,2}$ such that for any vertex $vin V(G)$ with $f(v)=emptyset$ the ...

Note on degree Kirchhoff index of graphs
(University of Isfahan, 2013-09-01)The degree Kirchhoff index of a connected graph $G$ is defined as the sum of the terms $d_i,d_j,r_{ij}$ over all pairs of vertices, where $d_i$ is the degree of the $i$-th vertex, and $r_{ij}$ the resistance distance ...

Energy of binary labeled graphs
(University of Isfahan, 2013-09-01)Let $G$ be a graph with vertex set $V(G)$ and edge set $X(G)$ and consider the set $A={0,1}$. A mapping $l:V(G)longrightarrow A$ is called binary vertex labeling of $G$ and $l(v)$ is called the label of the vertex $v$ ...

Two-out degree equitable domination in graphs
(University of Isfahan, 2013-09-01)An equitable domination has interesting application in the context of social networks. In a network, nodes with nearly equal capacity may interact with each other in a better way. In the society persons with ...

On the unimodality of independence polynomial of certain classes of graphs
(University of Isfahan, 2013-09-01)The independence polynomial of a graph $G$ is the polynomial $sum i_kx^k$, where $i_k$ denote the number of independent sets of cardinality $k$ in $G$. In this paper we study unimodality problem for the independence ...

On the nomura algebras of formally self-dual association schemes of class $2$
(University of Isfahan, 2013-09-01)In this paper, the type-II matrices on (negative) Latin square graphs are considered and it is proved that, under certain conditions, the Nomura algebras of such type-II matrices are trivial. ...
