Title: On Lindelof scattered subspaces of nice sigma-products

Abstract: We will show that there exists an Eberlein compact space K such that some Lindelöf subspace of K fails to be a Lindelöf Σ-space. We also prove that any scattered Lindelöf subspace of a σ-product of first countable spaces is σ-compact. It is established that if X is the Gδ-modification of a scattered compact space, then ext(Cp(X))=ω.
