Kink Collision in the Noncanonical Model: A Model with Localized Inner Structures
I. Takyi, S. Gyampoh, B. Barnes +2
We study collisions of kinks in the one-space and one-time dimensional noncanonical nonintegrable scalar model. We examine the energy density of the kink, and we find that,…
An Optimal Control Model of transmission dynamics of COVID-19 in Ghana
Samuel Okyere, Joseph Ackora-Prah, Ebenezer Bonyah +1
Almost every country in the world is battling to limit the spread of COVID-19. As the world strives to get an effective medication to control the disease, appropriate intervention…
A mathematical model of COVID-19 with an underlying health condition using fraction order derivative
Samuel Okyere, Joseph Ackora-Prah, Ebenezer Bonyah +1
Studies have shown that some people with underlying conditions such as cancer, heart failure, diabetes and hypertension are more likely to get COVID-19 and have worse outcomes. In…
Fractional Optimal Control Model of SARS-CoV-2 (COVID-19) Disease in Ghana
Samuel Okyere, Joseph Ackora-Prah, Kwaku Forkuoh Darkwah +2
Research focus on optimal control problems brought on by fractional differential equations has been extensively applied in practice. However, because they are still open-ended and…
A Mathematical Model of Transmission Dynamics of SARS-Cov-2 (Covid-19) with an Underlying Condition of Diabetes
Samuel Okyere, Joseph Ackora-Prah, Ebenezer Bonyah
It is well established that people with diabetes are more likely to have serious complications from COVID-19. Nearly 1 in 5 COVID-19 deaths in the African region are linked to diab…
Scattering of Kinks in Noncanonical sine-Gordon Model
I. Takyi, B. Barnes, H. M. Tornyeviadzi +1
In this paper, we numerically study the scattering of kinks in the noncanonical sine-Gordon model using Fourier spectral methods. The model depends on two free parameters, which co…
Vacuum Polarization Energy of the Kinks in the Sinh-Deformed Models
I. Takyi, B. Barnes, J. Ackora-Prah
We compute the one-loop quantum corrections to the kink energies of the sinh-deformed and models in one space and one time dimensions. These models are constructed…
A Caputo based SIRS and SIS fractional order models with standard incidence rate and varying population
E. Okyere, J. Ackora-Prah, F. T. Oduro
In the present work, we have introduced and studied two epidemic models that are constructed with Caputo fractional derivative. We considered standard incidence rate and varying po…
