Talk:Grothendieck ring

Redirecting to G-ring hides the usage regarding a tensor category
The Grothendieck ring of a tensor category (e.g., of modules over an artinian ring such as a finite group ring) is the Grothendieck group of the category, with a multiplication structure induced from the tensor product operation. This is an important meaning for the phrase "Grothendieck ring". Issai1875 (talk) 19:53, 10 August 2023 (UTC)
