特色品种
Distinguished Varieties
摘要:
一个独特的变种是一个变种,通过独特的边界退出双盘。我们发现,安藤的不等式交换矩阵收缩可以锐化看最大模上的一个杰出的品种,而不是整个bidisk。我们证明了双圆盘极值Pick问题的唯一性集总是包含一个独特的品种。
英文摘要:
A distinguished variety is a variety that exits the bidisk through the distinguished boundary. We show that Ando's inequality for commuting matrix contractions can be sharpened to looking at the maximum modulus on a distinguished variety, not the whole bidisk. We show that uniqueness sets for extremal Pick problems on the bidisk always contain a distinguished variety.
