本文研究交错实 *-代数上的切片正则函数,证明可在适当子集上指定零点与函数值,并由此得出轴对称域上存在不可延拓的此类函数。
AI 中文摘要
切片正则函数是全纯函数的一种推广,其中考虑交错实 *-代数而非复数域。对于此类函数,我们证明在适当子集上可以指定零点集和函数值。作为推论,我们证明对于任何轴对称域,存在切片正则函数,其(由于零点集的性质)不能延拓到更大的此类域。
英文摘要
Slice regular functions are a generalization of holomorphic functions where alternative real $*$-algebras are considered instead of the field of complex numbers. For such functions we show that zero sets and function values on suitable subsets may be prescribed. As a consequence, we show that for any axially symmetric domain there exist slice regular functions which (due to the nature of its zero set) can not be extended to a larger such domain.
