The realizations of finite-dimensional Lie algebras of smooth tangent vector fields on circle are described.The ``canonical'' realizations of two-dimensional noncommutative algebra, as well as the algebra $\mathfrak{sl}(2,\mathbb R)$ are constructed. It is shown that any realization of these algebras by smooth vector fields is reduced to one of a ``canonical'' realization by piecewise-smooth global transformations of circle onto itself.Formulas for calculating the number of non-equivalent realizations are obtained. |
