Description
Summary:	The formation ofearly‐type dwarf(dE) galaxies, the most numerous objects in clusters, is believed tobe closely connected to the physical processes that drive galaxy cluster evolution, like galaxy harassment and ram‐pressure stripping. However, the actual significance ofeach mechanism for building the observed cluster dE population is yet unknown. Several distinct dE subclasses were identified, which show significant differences in their shape, stellar content, and distribution within the cluster. Does this diversity imply that dEs originate from various formation channels? Does “cosmological” formation play a role as well? I try to touch on these questions in this brief overview of dEs in galaxy clusters (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
