We study a dual-type problem to generalized Christoffel function. The solution is connected with other extremal problems in the $H^p$ space of analytic functions on the unit circle considered by Macintyre, Rogosinski and Shapiro.

Christoffel函数的双重型问题

我们研究了广义Christoffel函数的双重类型问题。该解决方案与其他极端问题有关$H^p$ Macintyre，Rogosinski和Shapiro考虑的单位圆上的解析函数空间。
