The Kronecker quiver and affine sl2
In the 80s Drinfel'd discovered a "new presentation" of an affine
quantum group, which despite its initially daunting nature proved
extremely useful in the study of finite dimensional representations.
We will show that, at least in the case of sl2, this presentation
can be understood from the perspective of the Hall algebra of the
