Invariance of C*‐Algebraic Properties Under a Twisted Product
In this paper, we investigate the structure of a twisted C*‐algebra , built on a unital C*‐algebra using a central projection and a unitary . The operations are defined as and . A key insight we uncover is that this twisted setup is ‐isomorphic to the direct sum . Building on that isomorphism, we offer detailed descr...
