Abstract: The goal of this presentation is to introduce the Ext functor, and to expound on its interpretations and properties. The material will be introduced starting from the very basics, advancing with a specific focus on derived functors and, in particular, the Ext functor. Special attention will be given to the relation between this object and the equivalence classes of short exact sequences of modules over a given ring.
