摘要 设G是复平面C上的单连通区域,在研究G上的Carleson测度和多项式在G上的Hardy空间Hq(G)中的稠密性问题时,建立起了两者之间的一种等价关系.用Carleson测度给出了多项式在Hq(G)中稠密的充要条件,也刻画了所有那些使得在其上的Carleson测度和Carleson不等式等价的单连通区域. Let G be a simply connected domain in the complex plane C. This paper studies Carleson measures on G and the density problem of, P, the set of the polynomials in the Hardy spaces H^q (G), and gives a necessary and sufficient condition for the density of problem of P in H^q(G) in terms of Carleson measure, and also characterizes all simply connected domains on which the Carleson measure and the Carleson measure inequality are equivalent.
