Abstract
The affine evaluation map is a surjective homomorphism from the quantum toroidal (Formula Presented) to the quantum affine algebra (Formula Presented) at level κ completed with respect to the homogeneous grading, where q2 = q2 and q3n=κ2. We discuss En′(q1,q2,q3) evaluation modules. We give highest weights of evaluation highest weight modules. We also obtain the decomposition of the evaluation Wakimoto module with respect to a Gelfand–Zeitlin-type subalgebra of a completion of En′(q1,q2,q3), which describes a deformation of the coset theory (Formula Presented).
