Review of a Study of Soft Fields

I. A. Onyeozili*

Molodtsov in 1999 introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty about vague concept. In this paper, we present the definition of soft field and soft subfield with illustrative examples. Some properties of soft fields and soft subfields are investigated.

Estimates for some Classes of Analytic Functions Associated with Pascal Distribution Series, Error Function, Bell numbers and q-Differential Operator

E. A. Oyekan*, A. O. Lasode

In this paper, we considered two classes of analytic functions. The classes are associated with Pascal distribution series, error function, Bell numbers and q-derivative operator. Some early coefficient estimates for the classes were established and some interesting nexus between our estimates and that of some earlier known classes were presented.

Adomian Decomposition Method (ADM) Solution of Boundary Layer Flow Past a Stretching Plate with Heat Transfer, Viscous Dissipations, and Grashof Number

Yusuf A*, Jiya M., Tsadu S

The research work focuses on the solution of Magnetohydrody namics (MHD) boundary layer flow past a stretching plate with heat transfer and viscous dissipation. The non-linear of momen tum and energy equation are transformed into ordinary differential equation using similarity transformation, the resulting equations were solved using Adomian decomposition method (ADM). An attempt has been made to ...

The Stability of Solution of a Multifactor Capital Asset Management Model

T. Latunde*, R. O. Folaranmi, A. A. Ayoade

This work focuses on the presentation of a multifactor asset management model based on the uncertainty theory, and the stability of the multifactor model solution to the formulated state design of a real-life situation of management of capital assets. The model is designed as an optimization problem based on the assumption of the Hyperbolic Absolute Risk Aversion utility function. The formulated m...

A Mathematical Model for Measles incorporating Public enlightenment, Vaccination with Testing and Measles Therapy

S. Magaji Abubakar*, PATRICK NOAH OKOLO, AGABI SIMON ANDREW, USENI PAUL F

A deterministic mathematical model of measles infection incorporating public enlightenment, vaccination of susceptible humans, with testing and measles therapy of exposed humans, with testing and measles therapy of exposed human is developed. The disease-free equilibrium (DFE) state of the model was determined and used to compute the basic reproduction numberR0, as a threshold for effective diseas...

MHD Mixed Convective Flow of a Second Grade Fluid in the Presence of Nonlinearized Thermal Radiation, Thermal diffusion and Diffusion thermo Effects

I. G. Baoku*, K. I. Falade

The implicit finite difference method of Crank-Nicolson type is employed to examine heat and mass transfer in a transient magnetohydrodynamic mixed convective flow of a viscoelastic second grade fluid past a vertical porous plate in the presence of nonlinearized thermal radiation, thermal diffusion and diffusion thermo effects. The governing coupled nonlinear time-based partial differential equati...

A Class of Two-Step Obrechkoff-Type of Hybrid Block Method for Solving Initial Value Problems in Ordinary Differential Equations

L. A. Ukpebor*, Lawrence Osa Adoghe, I. E. Airemen

In this paper, we derived A Class of Two-Step Obrechkoff-Type of Hybrid Block Method for Solving Initial Value Problem (IVP) in Ordinary differential equations (ODEs) by collocation and interpolation techniques. The analysis of the proposed scheme shows that it is zero stable, convergent and consistent. Numerical examples are also presented to show that the method compared favorably with results o...

Approximate Analytical Methods for the Solution of Fractional Order Integro-differential Equations

A. I. Alaje*, M. O. Olayiwola, M. O. Ogunniran, J. A. Adedeji, K. A. Adedokun

In this paper, two numerical methods for obtaining the so lution of fractional order integro-differential equations were disscussed. The modified variational iteration method (MVIM) which is a modified general Lagrange multiplier method and the modified homotopy perturbation method (MHPM) were applied to solve both linear and non-linear cases of fractional order integro-differential equations. Alt...

Functions Defined by Product of Geometric Expressions

F. M. JIMOH*, Kunle Oladeji Babalola

We introduce a new class, Jα n(β), of analytic and univa lent functions defined by product of geometric expres sions. The univalence of functions in the new class as well as sufficient inclusion condition is established. The radius of convexity for the class J1 0(β) is also obtained.
