On integral Witt equivalence of algebraic number fields. (English) Zbl 0870.11022
The paper deals with the Witt equivalence and EOP-Hilbert-symbol equivalence of two algebraic number fields. The integral Witt equivalence and the complete classification of quadratic number fields are included, too. The proofs use the so-called Harrison criterion.
