摘要:
Ivanov 多维示性函数是将单复变解析函数中著名的示性函数概念推广至多复变解析函数。我们为其证明了三角凸性的类似结论。此外,我们证明了该估计是精确的。该证明基于扇形 Fourier 反演公式的多维类比。
英文摘要:
Multidimensional indicator after Ivanov is a generalization of the notion of indicator, that is well-known for analytic functions in one complex variable, to analytic functions in several complex variables. We prove an analogue of trigonometric convexity for it. Additionally, we show that our estimate is sharp. The proof is based on the multidimensional analogue of the sectorial Fourier inversion formula.
