On representations of quantum affine ${\mathfrak{s}\mathfrak{l}}_2$

We study tensor products of two-dimensional evaluation $U_q{\widehat{\mathfrak{s}\mathfrak{l}}}_2$-modules at generic values of $q$, $U_q{\widehat{\mathfrak{s}\mathfrak{l}}}_2$ homomorphisms between them, and closely related subjects.
