### Γ-invariant ideals in Iwasawa algebras

Abstract:

Let k G be the completed group algebra of a uniform pro-p group G with coefficients in a field k of characteristic p. We study right ideals I in k G that are invariant under the action of another uniform pro-p group Γ. We prove that if I is non-zero then an irreducible component of the characteristic support of k G / I must be contained in a certain finite union of rational linear subspaces of Spec gr k G. The minimal codimension of these subspaces gives a lower bound on the homological heigh...
