We introduce and study the quantum toroidal algebra E m|n (q 1 , q 2 , q 3 ) associated with the superalgebra gl m|n with m = n, where the parameters satisfy q 1 q 2 q 3 = 1.We give an evaluation map. The evaluation map is a surjective homomorphism of algebras E m|n (q 1 , q 2 , q 3 ) → U q gl m|n to the quantum affine algebra associated with the superalgebra gl m|n at level c completed with respect to the homogeneous grading, where q 2 = q 2 and q m−n 3 = c 2 . We also give a bosonic realization of level one E m|n (q 1 , q 2 , q 3 )-modules.
Quantum toroidal gl m|nAssume m, n ≥ 1 and m = n. In this section we introduce the quantum toroidal algebra associated with gl m|n , denoted by E m|n , and collect a few properties.2.1. Definition of E m|n . Fix d, q ∈ C × and define
