Group theory forms a cornerstone of modern algebra, providing a structured framework for analysing symmetries in mathematics, physics and beyond. A group is a set coupled with an operation that ...

Informally, a dynamic system is any physical system that evolves with time (e.g., a pendulum, a planet orbiting the sun, the weather, etc). From a more mathematically precise perspective, one can ...

We shall introduce the approximate representability and the Rohlin property for coactions of a finite dimensional C*-Hopf algebra on a unital C*-algebra and discuss their basic properties. We shall ...
