Abstract.For two commutative quadratic extensions over a commutative ring,if the trace forms are isometric then are these algebras isomorphic?If 2 is a non-zerodivisor then the answer is yes.If 2=0,the answer is no.And on the other case,we shall give some examples.2つの2次拡大多元環について,trace formが計量同型ならば多元環として同型であろうか.この問題の解答を与えた
