Let X and Y be compact hyper-Kahler manifolds deformation equivalence to theHilbert scheme of length n subschemes of a K3 surface. A cohomology class intheir product XxY is an analytic correspondence, if it belongs to the subringgenerated by Chern classes of coherent analytic sheaves. Let f be a Hodgeisometry of their second rational cohomologies with respect to theBeauville-Bogomolov-Fujiki pairings. We prove that f is induced by an analyticcorrespondence. We furthermore lift f to an analytic correspondence F betweentheir total rational cohomologies, which is a Hodge isometry with respect tothe Mukai pairings, and which preserves the gradings up to sign. When X and Yare projective the correspondences f and F are algebraic.

Rational Hodge isometries of hyper-Kahler varieties of K3[n]-type are algebraic
