Popis: Let Γ be one of the N2-dimensional bicovariant first-order differential calculi on the quantum groups O q (N) or Sp q (N), where q is not a root of unity. We show that the second antisymmetrizer exterior algebra s Γ∧ is the quotient of the universal exterior algebra u Γ∧ by the principal ideal generated by θ∧θ. Here ∧ denotes the unique up to scalars bi-invariant 1-form. Moreover, θ∧θ is central in u Γ∧ and u Γ∧ is an inner differential calculus.
