• Rational orthogonal similarity
• p-Adic numbers

This paper is concerned with a conjecture of Friedland [S. Friedland, Rational orthogonal similarity of rational symmetric matrices, Linear Algebra Appl. 192 (1993) 109-114]. A method for constructing counterexamples to the above conjecture is provided.
