Charles Weibel authored an exposition of <bilinear forms> over a <field>. It develops diagonalization and the classification of <symmetric bilinear forms>, including the real signature described by <Sylvester's law of inertia>. These classifications explain why changing a <basis> can simplify a form without removing invariants such as its numbers of positive and negative squares.<Bilinear Forms over a Field by Charles Weibel>[Pages 2–3]{ref}
