Abstract
A natural definition of q-deformation of Virasoro and superconformal a lgebras is proposed. New Lie algebraic symmetries are shown to describ e the lattice version of the original theory. On the classical (Poisso n brackets) level these two-loop algebras are shown to be isomorphic t o the Faddeev-Takhtadjan-Volkov lattice Virasoro algebra.
