摘要翻译:
研究了R^n上二次型的非对角范式,特别是对n=3的非对角范式。对于这种情况,证明了规范形集是一个5维子流形在\r^5的2维子空间的6维Grassmannian上的闭包。

英文摘要:
We investigate the non-diagonal normal forms of a quadratic form on R^n, in particular for n=3. For this case it is shown that the set of normal forms is the closure of a 5-dimensional submanifold in the 6-dimensional Grassmannian of 2-dimensional subspaces of \R^5.
