Subclasses of Partial Contraction Mapping in Semigroup of Linear Operators

K. Rauf*, A. Y. Akinyele, S. O. Makanjuola

Some properties of C0-Semigroup are investigated and are used to derive some characteristics of ω-Order Preserving and Reversing Partial Contraction Mapping where homo geneous, inhomogeneous and regularity of mild solution for analytic semigroups are engaged. Furthermore, the new sub classes performed exactly like semigroup of linear operators.

Radial Solution of the Monge-Amp`ere Equation on R3 and R4

Riadh JELLOUL*

In this paper, we determine radial solutions of the Monge-Amp`ere equation on R3 and R4 using a symplectic changeof variables. This transformation simplifies the formulationof the equation and allows it to be expressed in radialform, thereby reducing the problem to an associated ordinarydifferential equation. The existence and uniqueness of thesolutions are established and explicit expressions are...

Global Solvability of Navier-Stokes Equations with Temperature in Infinite Channel

Peter Anthony*, D. Hyuk Isaac, S. Magaji Abubakar, M. Gyuk Philibus

This paper determines the global, in time, solvability ofNavier-Stokes equation coupled with temperature in a Poincare-like unbounded domain. Existence, uniqueness and furtherregularity of solutions were obtained for the full Bousinesqsystem in uniformly local spaces. We have used themaximum principle for temperature to establish the cardinalproperties of this illusive phenomena of turbulence.

Efficient k-Derivative Methods for Lane-Emden Equations and Related Stiff Problems

M. O. Ogunniran*, Y. Haruna, R. B. Adeniyi

Lane-Emden equations are one of singular classes of problems in mathematical physics. Existing methods for this class of problems are series and analytical methods. This study focuses on the exploration of the possibility of a class of multi-derivative methods for approximating its solution. Taylor’s series expansion was applied on a new multi-derivative backward differenti ation formula to obtain...

Chemical reaction effects on hydromagnetic flow of a radiating and dissipative fluid past a tilted stretching sheet

Peter F. FASOGBON*, Rasheed A ADETONA

This paper probes into the chemical reaction e ects on steadyhydromagnetic ow of an incompressible viscous electricallyconducting, radiating and dissipative uid past a tilted stretchingsheet in the presence of heat source. The governing boundarylayer equations are first transformed into a non-dimensional formusing suitable similarity variables and the resulting system ofordinary di erential equati...

Application of Assignment Model in Optimizing Cost of a Building Project

Nyor Ngutor*, Olaniyan Toyin, Ladi Kevin

The study sought to minimize the total cost of building a three bed-room Detached House in Minna. An Assign ment problem was formulated and using Hungarian solu tion method, a realistic result was obtained. The sighting study with unpopular scenario in building recommended the sum of N3,885,000 which can be used to build a house of the type and specifications as provided in the study.

Efficiency of Simpson’s Rule; A Case Study of Unilorin Land Area

Ayinla Ally Yeketi*, Isola Olatomiwa Oluwadamilare

Simpson’s rule, a numerical integration technique, provides anefficient method for estimating the area of an irregularly shapedlarge landmasses when analytical solutions are impractical. Thisstudy applies Simpson’s 13 , 38 and hybrid rules to determine thearea of the University of Ilorin landmass. The hybrid method,combining the 13 and 38 rules, proves to be more efficient due to itsflexibility wi...
