WitrynaExt takes direct sums ... Then Ext commutes with localization, in the sense that for every multiplicatively closed set S in R, ... The Baer sum is an explicit description of … Witryna3 mar 2024 · We use derived localization of the bar and nerve constructions to provide simple proofs of a number of results in algebraic topology, both known and new. This includes a recent generalization of Adams’s cobar-construction to the non-simply connected case, and a new algebraic model for the homotopy theory of connected …

Witrynaa ring R have a representation as a subdirect sum of rings of some specified kind. The main part of this address will be devoted to giving partial answers to certain specific questions of this general type. The earliest references to infinite direct sums of rings or to sub-direct sums of any type are Prüfer [24],1 Krull [14] and Köthe [il, 12].

Certifico que la present … WitrynaThe question is then nothing but the fact that tensor product commutes with arbitrary direct sums (see e.g. this wiki page "distributive property"). Related Question WitrynaThe first is the generally more accessible K(n)-localization and the second is the closely related T(n)-localization. It is an open problem whether the two families of localizations coincide. One of the main reasons that the K(n)-local category is more amenable to computations is the existence of well understood Galois extensions of the K(n ... how to increase video speed in youtube
