A new approach to bounded linear operators on C(ω*)

Magdalena Grzech


We discuss recent results on the connection between properties of a given bounded linear operator of C(ω*) and topological properties of some subset of ω* which the operator determines. A family of closed subsets of ω*, which codes some properties of the operator is defined. An example of application of the method is presented.
