The Nigerian Journal of Mathematics and Applications (NJMA) is a double-blind peer-reviewed, open-access journal published three times a year by the Mathematical Association of Nigeria (MAN). It publishes original research across all areas of mathematics and its applications — from numerical analysis, functional analysis and semigroup theory to fluid dynamics, mathematical biology, statistics, optimisation and mathematics education.
NJMA is the research journal of the Mathematical Association of Nigeria. It considers submissions from mathematicians anywhere in the world and judges them on the same terms wherever they come from, giving that work a permanent, freely accessible home and holding it to the standard of proof and analysis the subject demands.
The editors give higher recognition to papers that combine sound mathematical concepts with applications, and to mathematics motivated by the prospect of potential application. That preference shows in what the journal prints: block and hybrid integrators for stiff systems alongside boundary-layer flow over a stretching sheet, fixed point theorems alongside epidemic models for hepatitis B and Ebola, semigroup theory alongside the scheduling of machines and the routing of water. Pure mathematics is welcome on its own terms — but mathematics that reaches for a use is what this journal most wants to carry.
Everything NJMA publishes is free to read, download and share from the day it appears. There is no subscription, no paywall and no embargo period. Publication is funded by author charges rather than by readers, and those charges are set out in full under Fees and Charges in the Author Guidelines.
The journal's back catalogue is being digitised and added to this site volume by volume. Volume 23 (2014) onwards is available now in the Archives, and articles published from Volume 36 (2026) are assigned a DOI and deposited with Crossref.
The subject areas we cover, the methods we accept and the kinds of manuscript that fall outside our remit are set out on the Aims & Scope page. Submissions are made through this website, and the Author Guidelines carry everything an author needs: manuscript types and length limits, formatting and referencing, how peer review works, fees, publication ethics and copyright.
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...
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. T...
In this paper, we prove the existence of an extremal functionthat minorizes all admissible functions with zero supremum ona non-toric Fano manifold, namely the complex GrassmannianG2,4(C) blown up along P1(C). The functions considered areinvariant under a suitably chosen automorphism group. Thislowe...
The key idea behind solving well known applicable problems is to reformulate the problems as finding a fixed point of a suitably defined mapping. The theory of variational inequalities and equilibrium problems involving some operators with monotonicity conditions have received remarkable development...
This study investigates non-slip hydromagnetic laminar dissipation flow with Arrhenius kinetics in binary reactions characterized by reaction order and variable properties within an unbounded isothermal device. The partial differentiation model is nondimensionalized to a thermofluidic dimensionless ...
Cerebrospinal meningitis (CSM) remains a major public health challenge in sub-Saharan Africa. This study analyzed records of 390 suspected CSM patients (2020–2023) from Aminu Kano Teaching Hospital, Nigeria, using sex, age, and month as explanatory variables. Logistic regression and ordinary least s...
In Almon distributed lag modeling, presence of multicollinearity, choice of appropriate approximating polynomial of suitable degree and choice of optimal truncation lag-length required for the implementation of Almon distributed lag model constitute three major problems confronting Almon distributed...
This paper is proposing a novel technique that generates an unpredictable digit-size at every time of authentication. In this technique, neither the authentic user nor the hacker can have the prior knowledge of the digit-size not to think of the combinatorial (sequence or random order) of the antici...
Fixed point theory in generalized metric spaces has received considerable attention due to its wide applicability in nonlinear analysis. In this work, we introduce a new class of nonlinear contractions, termed qpb–Condensed Ciri´c–Reich–Rus type ˇ contractions (qpb − CCRR), defined on complete quasi...
Polynomials associated with topological indices are defined from graph-based indices with their coefficients and exponents derived from these values. This paper presents formulae for such polynomials for cycle Cn, wheel Wn, path Pn, complete graph Kn and complete bipartite graph Km,n. It is further ...
