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.

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

The functor G commutes with respect to direct limits (direct unions, resp. direct sums) if the homomorphisms ΓF are isomorphisms for all directed systems F(such that all vij are monomorphisms, resp. all direct sums). Let C be an additive category with direct limits.
