IRPSM is a method that extends the residual power series method (RPSM) to (BVPs) without requiring exact solution. The presented method is capable to handle both linear and nonlinear boundary value problems (BVPs) effectively. The solutions provided by IRPSM are compared with the actual solution and with the existing solutions. The results demonstrate that the approach is extremely accurate and dependable.</p>2022-03-21T00:00:00+00:00Copyright (c) 2022 Journal of Mathematical Analysis and Modelinghttps://www.sabapub.com/index.php/jmam/article/view/441Completely positive map from M4(C) to M5(C) on positive semidefinite Matrices2022-02-11T13:07:02+00:00Winda C.

However, characterization of the structure of the set of all positive maps is a challenge in mathematics and mathematical physics. We construct a linear positive map from M4 to M5 and state the conditions under which they are positive and completely positive (copositivity of positive).</p>2022-04-01T00:00:00+00:00Copyright (c) 2022 Journal of Mathematical Analysis and Modelinghttps://www.sabapub.com/index.php/jmam/article/view/332On Equivalence of the ap-Sequential Henstock and ap-Sequential Topological Henstock Integrals2021-08-17T20:42:19+00:00Victor Odalochi Iluebevictorodalochi1960@gmail.comAdesanmi Alao Mogbademuamogbademu@unilag.edu.ng<p>Let $X$ be a topological space and $\Omega \subset X$. Suppose $f:\Omega\rightarrow X$ is a function defined in a complete space $ \Omega $ and $ \tau $ is a vector in $ \mathbb{R} $ taking values in $X$. Suppose $ f $ is ap-Sequential Henstock integrable with respect to $\tau$, is $ f $ ap-Sequential Topological Henstock integrable with respect to $\tau$? It is the purpose of this paper to proffer affirmative answer to this question.</p>2022-06-15T00:00:00+00:00Copyright (c) 2022 Journal of Mathematical Analysis and Modelinghttps://www.sabapub.com/index.php/jmam/article/view/448Mathematical Modeling: A Study of Corruption among Students of Nigeria Tertiary Institutions2022-05-14T06:26:21+00:00A. O. Adeniranadeadeniran@fedpolel.edu.ngO. O. Olanegan adeadeniran@fedpolel.edu.ngO. S. Akinsola adeadeniran@fedpolel.edu.ng<p>Corruption is a slow poison damaging students and consequently societies and nations, virtually, all students of Nigerian tertiary institutions are exposed to corruption. In this study, an attempt is made to formulate the dynamics of corruption among students of Nigerian tertiary institutions. We describe mathematical modeling of corruption among students using an epidemiological compartment model. The population at risk of adopting corrupt ideology was divided into four compartments: S(t) is the susceptible class, E(t) is the Exposed class, C(t) is the Corrupted class and P(t) is the punished class. The positivity and boundedness of the model were established. The model possesses both corruption-free and endemic equilibrium. Likewise, the model exhibits threshold dynamics characterized by the basic reproduction number R0. The numerical implementation of the model reveals that corruption will persist among Nigeria students if the root cause were not eradicated.</p>2022-06-15T00:00:00+00:00Copyright (c) 2022 Journal of Mathematical Analysis and Modelinghttps://www.sabapub.com/index.php/jmam/article/view/424Male Circumcision: A Means to Reduce HIV Transmission between Truckers and Female Sex Workers in Kenya2022-06-04T05:28:00+00:00Ancent M. Kimuluancentk@gmail.comWinifred N. Mutukumutukuwinnie@gmail.comSamuel M. Mwalilisamuel.mwalili@gmail.comDavid Malonzadmalo2004@gmail.comAbayomi Samuel Okeokeabayomisamuel@gmail.com<p>Kenya records over 1.5 million cases of HIV-infected people with a prevalence of 4.8% among adults<br />in 2019, ranking Kenya as the seventh-largest HIV population in the world. A recent study showed that<br />55.9% of Kenyan truckers pay for sex in while 46.6% had a regular partner along their trucking route in<br />addition to a wife or girlfriend at home. The complexity in the sexual network of Truckers, which can be a<br />conduit for the widespread of HIV, necessitated the need to better understand the dynamics of transmission<br />of HIV/AIDS between truckers and female sex workers. In this study, a model is formulated for HIV/AIDS<br />dynamics along the Northern corridor highway in Kenya. The reproduction number, disease-free equilibrium<br />and endemic equilibrium points were determined and their stabilities were also determined using the nextgeneration<br />matrix method. The disease-free equilibrium is stable when R0u < 1, R0c < 1 and R0f < 1 while<br />the endemic equilibrium point is stable when R0u > 1, R0c > 1 and R0f > 1. It is found that circumcision can<br />be used as an intervention to minimize the infection of HIV among truckers and female sex workers.</p>2022-06-21T00:00:00+00:00Copyright (c) 2022 Journal of Mathematical Analysis and Modeling
