On the log-hyperconvexity index of pseudoconvex H$\ddot{o}$lder domains in $\mathbb{C}^n$

Autor: Yu, Tianlong

In this note we prove that every bounded pseudoconvex domain in $\mathbb{C}^n$ with H$\ddot{o}$lder boundary has positive log-hyperconvexity index which gives a positive answer to a question posed by Boyong Chen.

A multivariate version of Polya-Carlson theorem

Autor: Yu, Tianlong

Polya-Carlson theorem asserts that if a power series with integer coefficients and convergence radius 1 can be extended holomorphically out of the unit disc, it must represent a rational function. In this note, we give a generalization of this result
