We give necessary and sufficient conditions on the parameters s 1 , s 2 , …, s m , p 1 , p 2 , …, p m such that the Jacobian determinant extends to a bounded operator fromH p 1s 1× H p 2s 2× … × H p ms minto Z′. Here all spaces are defined on R n and 2⩽ m ⩽ n . In almost all cases the regularity of the Jacobian determinant is calculated exactly.
