We consider Mergelyan sets and Farrell sets for $$H^p$$$$(1\le p < \infty )$$ spaces in the unit disc for both the weak topology and the norm topology, and give a short proof of a theorem of Perez-Gonzalez which answers a question proposed by Rubel and Stray (J Approx Theory 37:44–50, 1983).

在 $$H^p$$ 空间中的联合逼近问题

对于弱拓扑和范数拓扑,我们考虑了单位圆盘中 $$H^p$$$(1\le p < \infty )$$ 空间的 Mergelyan 集和 Farrell 集,并给出了一个简短的证明Perez-Gonzalez 定理回答了 Rubel 和 Stray 提出的问题(J Approx Theory 37:44–50, 1983)。
