On the structure theory of the Iwasawa algebra of a p-adic Lie group

Abstract: This paper is motivated by the question whether there is a nice structure theory of finitely generated modules over the Iwasawa algebra, i.e. the completed group algebra, of a p-adic analytic group G. For G without any p-torsion element we prove that is an Auslander regular ring. This result enables us to give a good definition of the notion of a pseudo-null -module. This is classical when G = Z k p for some integer k ≥ 1, but was previously unknown in the non-commutative case. Then the category of -modules up… Show more

“…Thus there is a dimension theory for A-and B-modules, for a thorough treatment of which we refer the reader to [10] or [28]. The previous lemma shows that the canonical (co-)dimension filtrations of M ǫ A-mod R considered as A- similarly for B).…”

“…2.3]). This should be compared also with Chamarie's result 3.3-3.5 in [7]: While A S is "responsible" for the faithful modules the bounded ring A (X) covers the bounded modules (in the quotient category of A-mod modulo the Serre subcategory of pseudo-null A-modules, see [10] or [28]). …”

“…Assume that the last statement was not satisfied; among all codimensions of H i which violate this inequality, choose the maximal one, c. Among all i < d for which this codimension is achieved, choose the minimal one. Thus, the codimension of H i is c < d − i, but the codimension of H k for k < i is greater than c. The results of [63] imply that if X is of codimension c, then E j (X) = 0 for j < c, E c (X) is of codimension (exactly) c, and E j (X) is of codimension ≥ j for j > c. Now look at the Poincaré duality spectral sequence [17, Section 1.3]:…”
