http://informaticsjournals.com/index.php/jims/article/view/25448
In this paper, we investigate the similarity classes of linear transformations on a vector space using structure theorem for finitely generated modules over a principal ideal domain. We also establish formulae to count similarity classes with a given polynomial as a characteristic polynomial and to count total number of classes when the scalar field is finite.Puja BhartiJagmohan Tanti

http://informaticsjournals.com/index.php/jims/article/view/25449
In the light of Riemann open mapping theorem, if we map open unit disk U conformally onto a region then depending on the geometry of boundary of we can always extract a subclass of H[a, n] by subordinating various functionals of the function f ∈ H[a, n]. Depending upon the geometry of the range set attempts have been made to find some algebraic structure in such classes, for that Hankel determinant of coefficients of functions pertaining to these classes have been studied, bounds of various coefficients have been determined and also based on the subordination principle we have determined radius |z| < r ;z ∈ U for which f belongs to such a class. In this paper our focus would be on n−PS<sup>*</sup> defined as n − PS<sup>*</sup> = {f ∈ A : Re {zf<sup>'</sup>(z)/f(z)} > 0,|(zf<sup>'</sup>(z)/f(z))<sup>n</sup> - 1|<1}.Rajesh Kumar MauryaPoonam Sharma

2020-07-012020-07-01873-416517710.18311/jims/2020/25449Tolerance Approach to Sensitivity Analysis in Multiobjective Transportation Problem
http://informaticsjournals.com/index.php/jims/article/view/25450
This paper represents ordinary sensitivity analysis and tolerance approach to sensitivity analysis in supply and demand values of the multiobjective transportation problem. Our proposed approach allows simultaneous and independent changes in the supply and demand values. The aim of this paper is to find the ranges for each supply and demand value within which the changes can occur without affecting the current basis of the best compromise solution. We have used the best compromise solution obtained using fuzzy programming technique for the postoptimality analysis of the multiobjective transportation problem. The approach is illustrated by a numerical example.P. M. ParataneA. K. Bit

http://informaticsjournals.com/index.php/jims/article/view/25451
The concept of the covering energy of a poset is introduced and its bounds are given. We compute covering energy of some classes of posets like S<sub>n</sub>, 2<sup>n</sup>. The posets D<sub>k</sub> and D<sup>'</sup><sub>k</sub> are defined and two recurrence relations for the characteristic polynomials of these posets are obtained. The energies of the posets D<sub>1</sub>, D<sub>2</sub>, D<sub>3</sub>, D<sub>4</sub> and D<sub>5</sub> are explicitly computed. The existence of some eigenvalues for some type of D<sub>k</sub> and D<sup>'</sup><sub>k</sub> is proved.Madhukar M. PawarVandana P. Bhamre

http://informaticsjournals.com/index.php/jims/article/view/25453
In this paper, we establish some fixed point theorems and a coincidence point theorem for contractive type mappings in the framework of complete partial metric spaces and give some examples in support of our results. The results presented in this paper extend and generalize several results from the existing literature.G. S. Saluja

http://informaticsjournals.com/index.php/jims/article/view/23906
In this paper, we establish the algebraic structure of all cyclic and negacyclic codes of length 8<em>p</em><sup>s</sup> over the chain ring Fp<sup>m</sup> + uFp<sup>m</sup> in terms of their generator polynomials, where u<sup>2</sup> = 0 and s is a positive integer and p is an odd prime. We also find out the number of codewords in each of these cyclic codes. Besides this, we determine duals of cyclic codes and list self-dual cyclic and negacyclic codes of length 8<em>p</em><sup>s</sup> over Fp<sup>m</sup> + uFp<sup>m</sup>. Also, we determine μ and -constacyclic codes of length 8<em>p</em><sup>s</sup> over Fp<sup>m</sup> + uFp<sup>m</sup>.Saroj Rani

http://informaticsjournals.com/index.php/jims/article/view/25447
In this study a mathematical analysis has been carried out to scrutinize the unsteady boundary layer flow of an incompressible, rarefied gaseous flow over a vertical stretching sheet with velocity slip and thermal jump boundary conditions in the presence of thermal radiation. Using boundary layer approach and suitable similarity transformations, the governing partial differential equations with the boundary conditions are reduced to a system of non-linear ordinary differential equations. The resulting non-linear ordinary differential equations are solved with the help of fourth order Runge-Kutta method with shooting technique. The results obtained for the velocity profile, temperature profile, skin friction coefficient and the reduced Nusselt number are described through graphs. It is predicted that the velocity and temperature profiles are lower for unsteady flow and has an opposite effect for steady flow.Ram Prakash SharmaN. IndumathiS. SaranyaB. GangaA. K. Abdul Hakeem
