A remark on the integrals of motion associated with level $k$ realization of the elliptic algebra $U_{q,p}(s{l}_2^{)}$

T. Kojima, J. Shiraishi

We give one parameter deformation of level $k$ free field realization of the screening current of the elliptic algebra $U_{q,p}(s{l}_2^{)}$. By means of these free field realizations,…
