Toward a vertex operator construction of quantum affine algebras

Abstract: We describe a construction of the quantum-deformed affine algebras using vertex operators in the free field theory. We prove the Serre relations for the Borel subalgebras of quantum affine algebras; in particular, we consider the $\widehat{sl}_2$ case in detail. We also construct the generators corresponding to the positive roots of $\widehat{sl}_2$.

Keywords: quantum group, quantum affine algebra, free field theory, minimal model, Serre relations
