Centripetal operators and Koszmider spaces
We study properties of Koszmider spaces and introduce a related notion of weakly Koszmider spaces. We show that if the space K is weakly Koszmider and C (K) is isomorphic to C (L) then L is also weakly Koszmider, but the analogous result does not hold for Koszmider spaces. We also show that a connected Koszmider space is strongly rigid. © 2008 Elsevier B.V. All rights reserved.
