摘要: 把Frobenius度量dF(Z,W)推广到一般的酉不变度量dp, (k) (Z,W). 对于 p≥2 推导了它的具体表达式,对于 1 ≤ p 2给出猜测, 并对 p =1 ,l=2的情况给出证明.

Abstract: This paper extends the Frobenius metric dF( Z,W) to a general unitarily invariant metric dp,(k)( Z,W). Expressions are derived for p ≥ 2 and for p=1,l=2. And some conjecture is made for p=1, l≥ 3.-
