*M. Dickmann; F. Miraglia*

(1) Extending the classical
notion of matrix isometry of forms to a suitable notion of
\(T\)-isometry, where \(T\) is a
preorder of the given ring, \(A\), or \(T = A^2\).

(2) Introducing in this context three axioms expressing simple
properties of (value) representation of elements of the ring by
quadratic forms, well-known to hold in the field case.
