Neusel, M.D.Sezer, M.2016-02-082016-02-0820091073-2780http://hdl.handle.net/11693/22575We study separating algebras for rings of invariants of finite groups. We describe a separating subalgebra for invariants of p-groups in characteristic p using only transfers and norms. Also we give an explicit construction of a finite separating set for invariants of groups acting diagonally. © International Press 2009.EnglishSeparating invariants for modular P-groups and groups acting diagonallyArticle1945-001X
