 Title: WCG spaces and their subspaces characterized by suitable projectional skeletons

 Abstract  
While PRI (projectional resolutions of identity) are very good for performing several arguments in WCG spaces and around, they are not very convenient for characterizing classes of Banach spaces. While projectional skeletons - recently articulated by W. Kubis - can do this job well. For instance a big class of Plicko spaces consists exactly of those spaces which admit a commutative projectional skeleton (W. Kubis). In the seminar, we present characterizations of WCG spaces and their subspaces in a similar manner. Joint work with V. Montesinos.
