摘要：

Let R be a commutative, local, and principal ideal ring with maximal ideal in and residue class field F. Suppose that every element of 1 + m is square. Then the problem of classifying arbitrary symmetric matrices over R by congruence naturally reduces, and is actually equivalent to, the problem of classifying invertible symmetric matrices over F by congruence.
