Abstract
Poincare had generalised the Euler equation to any Lie algebra. We app ly the same method to the infinite dimensional Virasoro algebra to obt ain the KdV equation. We have discussed in a quite self-contained way the symmetries of the KdV equation and the Virasoro algebra and their interconnection.
