Una demostración del teorema de Cayley para grupos

In this work, we will prove Cayley theorem, using category theory. We will see a different proof than theone seen in a Group Theory course, in this case we will use a famous result in category theory called theYoneda lemma and then, to relate groups with such lemma we will take advantage of the fact that everygroup can be viewed as a category. This proof shows that Yoneda lemma is an extensive generalization ofCayley theorem for groups.
