Abstract
The work is devoted to a probably new connection between deformed Virasoro algebra and quantum affine algebra \(\mathfrak {sl}_2\). We give an explicit realization of Virasoro current via the vertex operators of the level 1 integrable representations of quantum affine algebra \(\mathfrak {sl}_2\). The same is done for a twisted version of deformed Virasoro algebra.
