A ring R with centre Z (R) is called compressible if Z (eRe) = eZ (R) e for any idempotent e of R. In this paper we shall give some examples of compressible group algebras and of noncompressible group algebras. These examples show that it is very difficult to judge the compressibility of a group algebra.
