We compute the cohomology spaces for the tautological bundle tensor the det
erminant bundle on the punctual Hilbert scheme X-[m] of a smooth projective
surface X on C. We show that for L vector bundle and A invertible vector b
undle on X, if H-q(X, A) = H-q(X, L x A) = 0 for q greater than or equal to
1, then the higher cohomology spaces on X-[m] of the tautological bundle a
ssociated to L tensor the determinant bundle associated to A vanish, and th
e space of global sections is computed in terms of H-0(A) and H-0(X, L x A)
. This result is motivated by the computation of the space of global sectio
ns of the determinant bundle on the moduli space of rank 2 semi-stable shea
ves on the projective plane, supporting Le Potier's strange duality conject
ure on the projective plane.
