H.有界对称域的玻尔定理

H. Bohr's theorem for bounded symmetric domains

Guy Roos

摘要:

Harald Bohr(1914)的一个定理指出,如果f是从单位圆盘到自身的全纯映射,则当|z| <1/3时,其泰勒展开式的绝对值之和小于1。1/3是最优的。刘泰顺和王剑飞(2007)在适当的意义下将这一结果推广到了四个经典级数的有界复对称域和多圆盘。Liu和Wang的结果可以推广到所有有界对称域,并给出了一个不依赖于分类的证明。

英文摘要:

A theorem of Harald Bohr (1914) states that if f is a holomorphic map from the unit disc into itself, then the sum of absolute values of its Taylor expansion is less than 1 for |z|<1/3. The bound 1/3 is optimal. This result has been extended in a suitable sense by Liu Taishun and Wang Jianfei (2007) to the bounded complex symmetric domains of the four classical series, and to polydiscs. The result of Liu and Wang may be generalized to all bounded symmetric domains, with a proof which does not depend on classification.
