摘要：
The inverse of the usual recursion operator for the Korteweg-de Vries equation is applied to the Galilean symmetry. A new family of non-local symmetries results. A symmetry algebra isomorphic to the semidirect sum of the loop algebra over sl((2,R) and a subalgebra of the Virasoro algebra is found.
