ABSTRACT:

In this paper, we defined dual Pell quaternions. Also, we investigated the relations between dual Pell quaternions which connected with Pell and Pell-Lucas numbers. Furthermore, we gave the Binet formulas and Cassini-like identities for these quaternions.

KEYWORDS: Pell number, Pell-Lucas number, Pell quaternion, dual Pell quaternion

ABSTRACT:

In this paper, we consider hydromagnetic convective flow of an electrically conducting visco-elastic fluid through a rotating porous channel taking hall current into account. The governing equations are framed using Brinkman model. The exact solutions of the velocity and the temperature distributions are evaluated analytically using Laplace transform technique and which consist of the both steady and transient states. Thought is centered on the physical character of the solutions, and the construction of the various kinds of boundary layers outward appearance on the plates. The ultimate steady state velocity and temperature distributions are numerically discussed for various values of the flow parameters. The shear stresses and the Nusselt number are tabulated and discussed.

ABSTRACT:

In this paper, we have presented a new method of construction of regular group divisible design. We also characterized a particular design of the series v = b =4 t+3, r=k+2 t+1, = t viz., v=b= 31, r=k=15, = 7 , considering nice block structure.

ABSTRACT:

Inflationary scenario in spatially homogeneous Bianchi Type IX space-time is investigated. To get the deterministic result, we have considered the potential V(ø) is constant and the scale factor R ~ eHt where H is Hubble constant. We findthat spatial volume (R3) increases exponentially. Thus inflationary scenario exists in Bianchi Type IX space time. The Higgs field decreases slowly. The expansion () is constant, shear () is zero and deceleration parameter (q) = – 1 which indicate that the model represents de-Sitter universe. The model also gives accelerating phase of the universe

ABSTRACT:

In this paper the concept of a Bipolar intuitionistic M fuzzy group and anti M fuzzy group is a new algebraic structure of a bipolar intuitionistic M fuzzy subgroup of a M fuzzy group and anti M fuzzy group are defined and related operators and level operators are investigated. The purpose of the study is to implement the fuzzy set theory and group theory of bipolar intuitionistic M fuzzy group and anti M fuzzy group. The relation between operation of level operators of bipolar intuitionistic M fuzzy group and bipolar intuitionistic anti M fuzzy group are established.
