How to Compute in Free Abelian Categories

ABSTRACT: Computing with universal mathematical objects can be interpreted as theorem proving. In this talk, we discuss the constructiveness of free abelian categories. Using a very concrete description of free abelian categories by Murray Adelman, we demonstrate how to validate homological lemmata like the Snake lemma or the five lemma computationally.
