Abstract: A natural definition of the $q$-deformation of the Virasoro and superconformal algebras is suggesteded. New Liealgebraic symmetries describe a lattice version of the continual theory. A close link between the deformation constructed in this paper and the lattice version of the Faddeev–Takhtadjian–Volkov Virasaro algebra is shown. Bibl. 18 titles.
