Let be a connected graph. The litact graph m(G) of a graph G is the graph whose vertex set is the union of the set of edges and the set of cut vertices of G in which two vertices are adjacent if and only if the corresponding members of G are adjacent or incident. A dominating set D of m (G) is called a connected dominating set of m (G) if the induced subgraph is connected. The minimum cardinality of D is called the connected domination number of m (G) and is denoted by . In this paper, we initiate a study of this parameter. We obtain many bonds on in terms of vertices, edges and different parameters of G and not the members of m (G). Further we determine its relationship with other domination parameters.

A study of the effect of stratified Rivlin-Ericksen fluid on MHD free convection flow past a vertical porous plate with heat and mass transfer and neglecting induced magnetic field in comparison to applied magnetic field is investigated. The velocity, temperature and concentration distributions are derived and discussed numerically with the helps of graphs and tables. It is observed that velocity increases with the increase in Gr (Grashof number) and K (Permeability parameter), but it decreases with the increase in M(Magnetic parameter). The velocity increases with the increase in Visco-elastic parameter) up to y = 2, then decreases.

We present a general class of inhomogeneous cosmological models filled with perfect magneto fluid by assuming that the background space-time admits two space-like commuting killing vectors and has separable metric coefficients. The singularity structure of these models depends on the choice of the parameters and the metric functions. A number of previously known perfect fluid models follow as particular cases of this general class. Physical and geometrical features of these models are studied.

The aim of the present paper is to introduce and study the mixed summation-integral type operators having Baskakov and Beta basis functions in summation and integration, respectively. First, we estimate moments of these operators using hypergeometric series. Next, we obtain the basic point-wise convergence, a Voronovskaja type asymptotic formula.

In this paper we introduce the concepts of 1 S -near subtraction semigroups, that is near subtraction semigroups X satisfying the condition: for every a  X there exists x  X {0} such that axa  xa. We also discuss some of their properties and obtain certain characterisation theorems
