Conjugacy in Hyper Semi-dynamical Systems

The notion of conjugacy on hyper semi-dynamical systems is studied from algebraic and topological points of views. Topological join operations for a new approach to topological hypergroups are considered. By using topological join operations, topological conjugacy are studied. Hyper orbits and limit points as two invariant sets under conjugacy are deduced. 2000 Mathematical Subject Classification: 37B99, 20N20
