Differential calculus on Hopf Group Coalgebra
A. S. Hegazi, W. Morsi, M. Mansour
In this paper we construct the Differential calculus on the Hopf Group Coalgebra introduced by Turaev [10]. We proved that the concepts introduced by S.L.Woronowicz in constructing…
An Overview of Complex Adaptive Systems
E. Ahmed, A. S. Elgazzar, A. S. Hegazi
Almost every biological, economic and social system is a complex adaptive system (CAS). Mathematical and computer models are relevant to CAS. Some approaches to modeling CAS are gi…
On complex adaptive systems and terrorism
E. Ahmed, A. S. Elgazzar, A. S. Hegazi
Complex adaptive systems (CAS) are ubiquitous in nature. They are basic in social sciences. An overview of CAS is given with emphasize on the occurrence of bad side effects to seem…
On Persistence and Stability of some Biological Systems with Cross Diffusion
E. Ahmed, A. S. Hegazi, A. S. Elgazzar
The concept of cross diffusion is applied to some biological systems. The conditions for persistence and Turing instability in the presence of cross diffusion are derived. Many exa…
On Spatial Asymmetric Games
E. Ahmed, A. S. Hegazi, A. S. Elgazzar
The stability of some spatial asymmeric games is discussed. Both linear and nonlinear asymptotic stability of asymmetric hawk-dove and prisoner's dilemma are studied. Telegraph rea…
On Synchronization, Persistence and Seasonality in some Spatially Inhomogeneous Models in Epidemics and Ecology
E. Ahmed, A. S. Hegazi, A. S. Elgazzar +1
Recent studies in ecology and epidemiology indicate that it is important to include spatial heterogeneity, synchronization and seasonality in the theoretical models. In this work,…
