Query: Signatures of hermitian forms and "prime ideals" of Witt groups   In this paper a further study is made of $H$-signatures of hermitian forms,
introduced previously by the authors. It is shown that a tuple of reference
forms $H$ may be replaced by a single form and that the $H$-signature is
invariant under Morita equivalence of algebras with involution. The "prime
ideals" of the Witt group are studied, obtaining results that are analogues of
the classification of prime ideals of the Witt ring by Harrison and
Lorenz-Leicht. It follows that $H$-signatures canonically correspond to
morphisms into the integers.
