摘要：

To any graded Frobenius algebra A we associate a sequence of graded Frobenius algebras A([n]) so that there is canonical isomorphism of rings (H* (X; Q)[2])([n]) congruent to H* (X-[n]; Q)[2n] for the Hilbert scheme X-[n] of generalised n-tuples of any smooth projective surface X with numerically trivial canonical bundle.
