THE GROTHENDIECK GROUP OF FINITELY GENERATED MODULES

WebLet K (T) be the image of the Grothendieck group of T in the Grothen-dieck group of stmod(kG) (i.e., the subgroup of the Grothendieck group of stmod(kG) generated by the classes of the objects of T). Lemma 2.1. The group K (T) is generated by the class [k] of the trivial module and its order is equal to the order of a Sylow p-subgroup ofG. Proof. WebWe proved in a previous article that the bar complex of an -algebra inherits a natural -algebra structure. As a consequence, a well-defined iterated bar construction can be associated to any algebra over an -operad. I… WebCongruence is an example of an equivalence relation. The leftmost two triangles are congruent, while the third and fourth triangles are not congruent to any other triangle shown here. Thus, the first two triangles are in the same equivalence class, while the third and fourth triangles are each in their own equivalence class. fenix tk75 2012
