Abstract

We give one parameter deformation of level $k$ free field realization of the screening current of the elliptic algebra $U_{q,p} (\widehat{\mathfrak{sl}}_{2})$. By means of these free field realizations, we construct infinitely many commutative operators, which are called the nonlocal integrals of motion associated with the elliptic algebra $U_{q,p} (\widehat{\mathfrak{sl}}_{2})$ for level $k$. They are given as integrals involving a product of the screening current and elliptic theta functions. This paper give level $k$ generalization of the nonlocal integrals of motion given in [1].
