On deformed $\mathcal{W}$-algebras and quantum affine algebras
We discuss some aspects of the deformed W-algebras Wg^fe]-In particular, we derive an explicit formula for the Kac determinant, and discuss the center when t 2 is a primitive fc-th root of unity.The relation of the structure of Wg.tffl] to the representation ring of the quantum affine algebra U q …
