Re: Minimal abelian subcategory (corrected)

A message from Walter Mazorchuk: Dear Colleagues, thank you very much for your comments on my abelian envelope question. Because of my stereotype thinking I missed the point of the determination of the additive structure by the multiplicative one in the original formulation. The stereotype is based on the fact that I am a representation theorist and the origin of the question is in module categories, which are k-linear over some field k. So, the subcategory I am looking for should be a k-linear subcategory with the induced k-linear structure. Best, Walter
