✦ Synopsis

Let H H kQ be the Ringel᎐Hall algebra of affine quiver Q. All indecomposable Ž . representations of Q, which can be generated inside H H kQ by ''smaller'' represen-Ž . tations of Q, are classified; systems of minimal homogeneous generators of H H kQ are explicitly written out.

We show that it is possible to define reflection isomorphisms on the double of the (twisted) Hall algebra of a quiver. Combining these reflections with Fourier transform yields an alternative construction of Lusztig's braid group action on a quantum enveloping algebra.
