Dear all, This is to announce the Conference Algebras and Coalgebras, Tools for Geometry, Physics and Computer Science to be held in Cairo, Egypt March 25-30, 2006. Conference page: http://develop.aucegypt.edu/maths/index.html The aim of the conference is to gather mathematicians, mathematical physicists, and computer scientists working in areas closely related to the theory and applications of algebras and coalgebras. Besides exchanging information about the traditional applications of algebras to geometry, physics and computer science in this conference we want to highlight the usefulness of coalgebraic structures in these fields. They appear, for example, in quantum group theory, in symplectic geometry and quantum field theory, in non-commutative geometry, and in computer science.
