Let A be a simple unital AT algebra of real rank zero. It is shown below that the range of the natural map from the approximately inner automorphism group to KK(A,A ...

We examine the almost periodic part of the inner automorphism group of $\mathscr{B}(H)$ arising from a representation of a locally compact abelian group. Journal Information This monthly journal, ...

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 ...
