Heitmann ’ S Proof of the Direct Summand
نویسنده
چکیده
We describe the main ideas of Ray Heitmann’s proof of the Direct Summand Conjecture in dimension 3 for a ring of mixed characteristic [1]. In the first section we describe the main methods which are used and prove the necessary lemmas. In the second section we prove the main result of Heitmann’s paper. Finally, in the third section we give a proof of the Canonical Element Conjecture using this result.

T-dual Rickart modules
We introduce the notions of T-dual Rickart and strongly T-dual Rickart modules. We provide several characterizations and investigate properties of each of these concepts. It is shown that every free (resp. finitely generated free) $R$-module is T-dual Rickart if and only if $overline{Z}^2(R)$ is a direct summand of $R$ and End$(overline{Z}^2(R))$ is a semisimple (resp. regular) ring. It is sho...
متن کاملModules whose direct summands are FI-extending
A module $M$ is called FI-extending if every fully invariant submodule of $M$ is essential in a direct summand of $M$. It is not known whether a direct summand of an FI-extending module is also FI-extending. In this study, it is given some answers to the question that under what conditions a direct summand of an FI-extending module is an FI-extending module?

متن کاملOn H-cofinitely supplemented modules
A module $M$ is called $emph{H}$-cofinitely supplemented if for every cofinite submodule $E$ (i.e. $M/E$ is finitely generated) of $M$ there exists a direct summand $D$ of $M$ such that $M = E + X$ holds if and only if $M = D + X$, for every submodule $X$ of $M$. In this paper we study factors, direct summands and direct sums of $emph{H}$-cofinitely supplemented modules. Let $M$ be an $emph{H}...
متن کاملGeneralization of a going-down theorem in the category of Chow-Grothendieck motives due to N. Karpenko
We generalize this theorem when the motive M(X) ∈ CM(F ; Λ) is replaced by a direct summand (M(X), p) associated with a projector p ∈ EndCM(F ;Λ)(M(X)). The proof given by N. Karpenko in [2] cannot be used in the case where M(X) is replaced by a direct summand because of the use on the multiplicity ([1], §75) as the multiplicity of a projector in the category CM(F ; Λ) is not always equal to 1 ...
