We establish new characterizations for (pseudo) isometric extensions of topological dynamical systems. For such extensions, we also extend results about relatively invariant …
It is an old idea, going back to J. von Neumann and BO Koopman, 1 to assign to nonlinear dynamics on a (topological or measurable) state space corresponding linear operators on …

The representation theorems of Gelfand and Kakutani for commutative C*-algebras and AM- and AL-spaces are the basis for the Koopman linearization of topological and measure …
During the 1930s, researchers realized that an abstract dynamical system induces a group of linear operators acting on the space of square-integrable functions. For measure …
