Özet

Recently, the concept of (Formula presented.) -stable subspaces has played an important role in the characterization of polynomial rings, a topic that remains a challenging problem in algebraic geometry. It turns out that polynomial rings with more than one variables do not have any (Formula presented.) -stable subspaces over an algebraically closed field of characteristic zero. In this work, we characterize all (Formula presented.) -stable subspaces and (Formula presented.) -stable subalgebras of Grassmann algebras.
