# Quadratic relations of the deformed W-algebra for the twisted affine algebra A ( 2 ) 2

@inproceedings{Kojima2021QuadraticRO, title={Quadratic relations of the deformed W-algebra for the twisted affine algebra A ( 2 ) 2}, author={Takeo Kojima and September}, year={2021} }

We revisit the free field construction of the deformed W -algebra by Frenkel and Reshetikhin, Commun. Math. Phys. 197, 1-31 (1998), where the basic W -current has been identified. Herein, we establish a free field construction of higher W -currents of the deformed W -algebra associated with the twisted affine algebra A (2) 2N . We obtained a closed set of quadratic relations and duality, which allowed us to define the deformed W -algebra Wx,r (
