Multiplier Hopf group coalgebras from algebraic and analytical point of views
A. Hegazi, A. Elhafz
The Multiplier Hopf Group Coalgebra was introduced by Hegazi in 2002 [7] as a generalization of Hope group caolgebra, introduced by Turaev in 2000 [5], in the non-unital case. We p…
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…
