Grothendieck groups tri-exact category
Did you know?
A common generalization of these two concepts is given by the Grothendieck group of an exact category $${\displaystyle {\mathcal {A}}}$$. Simply put, an exact category is an additive category together with a class of distinguished short sequences A → B → C. The distinguished sequences are called … See more In mathematics, the Grothendieck group, or group of differences, of a commutative monoid M is a certain abelian group. This abelian group is constructed from M in the most universal way, in the sense that any abelian group … See more Generalizing even further it is also possible to define the Grothendieck group for triangulated categories. The construction is essentially similar but uses the relations [X] − [Y] + [Z] = 0 whenever there is a distinguished triangle X → Y → Z → X[1].
