Abstract
Let F(S1 ) be the space of tensor densities of degree (or weight) on the circle S1 . The space Dk ,µ(S1 ) of k-th order linear differential operators from F(S1 ) to Fµ(S1 ) is a natural module over Diff(S1 ), the diffeomorphism group of S1 . We determine the algebra of symmetries of the modules Dk ,µ(S1 ), i.e., the linear maps on Dk ,µ(S1 ) commuting with the Diff(S1 )-action. We also solve the same problem in the case of straight line R (instead of S1 ) and compare the results.
