Analysis of a Cournot-Bertrand Duoploy Game with Differentiated Products: Stability, Bifurcation and Control

R. Ahmed, N. Ali & F. M. Rana · Asian Research Journal of Mathematics · 2022

this work, we investigate a Cournot-Bertrand duopoly model with product differentiation between two different firms, where one company uses price as a decision variable and the other uses quantity. The stability of the Nash equilibrium point is investigated, and the role of the p...

Chemical Reaction and Radiative MHD Heat and Mass Transfer Flow with Temperature Dependent Viscosity Past an Isothermal Oscillating Cylinder

R. Ahmed, B. M. Jewel Rana, R. Uddin, M. M. Islam & S. F. Ahmmed · Physical Science International Journal · 2016

The numerical analysis is performed to examine the effects of magnetic, radiation and chemical reaction parameters on the unsteady heat and mass transfer flow past a temperature dependent viscosity of an isothermal oscillating cylinder. The governing coupled dimensional partial d...

Effect of Radiation on Unsteady MHD Free Convective Flow past an Exponentially Accelerated Inclined Plate

B. M. Jewel Rana, R. Ahmed, R. Uddin & S. F. Ahmmed · Journal of Advances in Mathematics and Computer Science · 2016

Unsteady MHD free convective flow past an exponentially accelerated inclined plate has been investigated in the presence of radiation, Dufour and Soret effect. The usual transformations have used to get governing equations in dimensionless form. Then the obtained dimensionless eq...
