Drinfeld realisation and highest weight representations of \(U_q(\mathfrak{osp}(1|2n)^{(1)})\)

The Drinfeld realisation of a quantum affine algebra is a quantum analogue of the loop algebra realisation of an affine Lie algebra. In this talk, we will first develop the Drinfeld realisations of quantum affine superalgebras \(U_q(\mathfrak{osp}(1|2n)^{(1)})\). This makes essential use of the notation of "Quantum correspondences". Then, by using the Drinfeld realisations, we will discuss the vertex operators for the level 1 irreducible integrable highest weight representations and the finite dimensional irreducible representations of \(U_q(\mathfrak{osp}(1|2n)^{(1)})\). This is joint work with Ruibin Zhang.
