Let $(A, G, \tau)$ be a noncommutative dynamical system, i.e. $A$ is a $C^\ast$-algebra, $G$ a topological group and $\tau$ an action of $G$ on $A$ by $^\ast ...

Many of the world's most important systems, such as the atmosphere, turbulent fluids, and even the motion of planets, behave unpredictably due to chaos and noise. Scientists often study these systems ...
