In this paper, we are proving a common fixed point theorem for mappings satisfying common E.A. like property in fuzzy metric space.We generalize the result of Jain et al.11, using rational inequality

In this paper, a theorem in connection with the unification of a class of trilateral generating relations for certain special functions with Tchebycheffpolynomial has been proved by group theoretic method, which in turn yields a number of theorems on trilateral generating functions involving classical orthogonal polynomials (see Section 3 of this paper).

In this paper we introduce a new concept in nano topology called as “Multi Star Granular Nano Topology” (MSGNT ) to study multi granulation. The algebraic structure on basic set theoretic operations and De-Morgan’s law are studied in MS-GNT. Further, we show that multi granulation is better than single granulation from a decision table in nano accuracy and nano degree of dependency following heuristic approach.

Tachibana (1965) has studied on harmonic tensor in compact Sasakian spaces. Chern (1966) has studied the geometry of G-structures. After than, Blair (1967) has studied the theory of Quasi-Sasakian structures. In this paper, we have studied on the topology of Almost Kaehlerian manifold and several theorems have been established. The notation and terminology in this paper will be the same as that employed in Blair (1967).

In this section we consider a bulk service GI/M(a,b)/1 Queue with multiple exponential Vacations. customers are served in batches according to the bulk service rule, in which at least a customers are needed to start a service and the maximum capacity of each service is b. When the server finishes a service and finds fewer than a customers in the system, he takes a vacation. When the server returns from a vacation and finds fewer than a customers in the system, the server immediately takes another vacation and continuous in this manner until the server finds at least a customers in the system.

This paper is devoted to nano ideal space and stipulated the concept of nano local function. Based on the Kuratowski’s closure operator the several forms of nano approximations were inquired in the nano ideal space. Different types of weak forms of nano open sets like nano semi I-open sets and nano αI-open sets were explored inaspects of distinct approximations. Further more, to emphasize our nano ideal space some examples are considered, which are efficacious for implementing this hypothesis in practical applications. Conclusively, We portayed the relation among the weaker form of nano open sets in nano ideal space.

This paper introduce and establish the properties of (1,2)*αψ-compact sets, (1,2)*αψ-locally compact sets, (1,2)*αψ-
Hausdorff spaces. Also we developed a main theorem called Baire Category Theorem by using weak open sets in bitopological spaces.

MHD flow of a Jeffrey fluid in a parallel plate channel is investigated when the walls are provided with non-erodible porous lining. The flow in the free flow region is governed by Jeffrey model and the flow in the porous region is described by Darcy law. The influence of the thickness of porous lining on the velocity field in the channel has been studied. The results are depicted graphically and discussed for various relevant parameters. It is observed that the velocity increases with the increase in Jeffrey parameter whereas the opposite behavior is noticed due to the increase in magnetic parameterM. It is also found that the skin friction is higher for non-Newtonian Jeffrey fluid when compared with Newtonian fluid.
