<p>Journal of the Nigerian Mathematical Society (JNMS)</p> <p>JNMS provides a means of communication and exchange of ideas among workers in mathematical sciences (mathematics, mathematical physics, statistics, computer science), and offers an effective method of bringing new results quickly to the public. By doing so the journal establishes an informal vehicle enabling the field of mathematical sciences to be understood in a broad sense. It will include theoretical and experimental results, and fundamental and practical research.<br /><br /></p>Nigerian Mathematical Societyen-USJournal of the Nigerian Mathematical Society0189-8965Monics and krib maps in Nayo Algebras
https://ojs.ictp.it/jnms/index.php/jnms/article/view/579
In this paper, nayo algebras are introduced. Properties of homomorphisms in relation to translation maps in nayo algebras are investigated. Moreover, monics and krib maps are introduced and studied in some classes of nayo algebrasEmmanuel Ilojide

https://ojs.ictp.it/jnms/index.php/jnms/article/view/580
<p>In this study, a metric is constructed on set of<br />some permutations on Sn called involution permutations. Some<br />topological properties of the metric permutation space were in-<br />vestigated. The study shows that every subset of the metric<br />involution permutation space is open, and the topological space<br />generated by the metric involution permutations space is Haus-<br />dorff, disconnected and normal.</p>Garba Abor IsaB.

https://ojs.ictp.it/jnms/index.php/jnms/article/view/376
In this paper, we study a forward-backward splitting algorithm for fixed points of a quasi-Bregman nonexpansive mapping, solution of equilibrium problem and zero points of the sum of families of accretive operators and $\alpha_i$-inverse-strongly accretive operators. We proved a weak convergence of the sequences generated by this algorithm in reflexive Banach space. Our result extend and improve important recent results announced by many authors. <br /><br />Bashir AliMohammed Suleman Lawan

https://ojs.ictp.it/jnms/index.php/jnms/article/view/621
<p>Presented here is a one-step second derivative intra-point block numerical method of uniform order eight for seeking the solution of stiff systems of ordinary di erential equations directly. The techniques of interpolation and collocation are used to build the continuous scheme from which the main method and additional methods were obtained. The convergence analysis of the proposed method to validate their e ffectiveness and reliability is presented. Some numerical examples both linear and non-linear are solved to demonstrate the effIciency of the method.</p>Umaru MohammedJamiu GarbaM. E Semenov

https://ojs.ictp.it/jnms/index.php/jnms/article/view/775
<p>A compartmental epidemic model proposed by Liancheng and Micheal [1] was investigated. A nonlinear incidence rate and treatment were taken into consideration. The bifurcation method introduced in [2] was being used to perform a bifurcation study, which is predicated on the use of the center manifold theory. The forward bifurcation was discovered. The Adomian Decomposition Method (ADM) was also used to approximate the solution of the problem's nonlinear system of differential equations. The computations were carried out using Maple, and the graphical results are given.</p>B. GbadamosiF. O. Akinpelu
