Abstract
We assume familiarity with group theory and discuss the technical background necessary
to construct and understand the functors Hom, Ext, T or and tensor on the category of
abelian groups, with special attention paid to Hom and Ext. In doing so, we hope to provide
an introduction to the study of category theory and homological algebra understandable to
an undergraduate with 1-2 semesters of abstract algebra.
