应用Zalcman引理研究了与导数有单向分担值的全纯函数族的正规族,得到了如下的结论:即:设F是区域D上的全纯函数,若对于任意的f∈F,都有f(z)=0→(z)=z→f''(z)=0且f(0)≠0,则F在D上正规(不再限制零点的级). 相似文献

研究全纯函数与其微分多项式分担函数,得到了如下的正规定则:设F是区域D内的全纯函数族,k是一正整数,h1(z),h2(z)在区域D内的解析,满足|h1(z)|2+|h2(z)|2≠0。若f∈F,f的零点重级至少为k,且f(z)=0|f(k)(z)|≤M(常数M〉0),(z)=αi(z)L(Z)=αi(z),i=1,2,其中L(z)=f∞(z)+α1(z)f(k-1)(z)+…+αk(z)f(z)为f的微分多项式,αi(z)(i=1,2,…,k,k≥1)在D内解析,那么F在D内正规。 相似文献

The maximally holomorphic functions of a bounded linear operator is introduced and applied to representthe spectrum and characterize the single--valued extension property. The well known results of quasi--nilpo-tent equivalent operators follow easily from the relation of their maximally holomorphie functions. 相似文献

In this paper, a class of strongly non-linear generalised Riemann-Hilbert problems for second-order elliptic system is studied.
By means of the theory of integral equations and using an explicit form of the solution, a reduction is made to a nonlinear
boundary value problem for two holomorphic functions. And using an approximation dealing with a solvable perturbed problems
and suitable prior estimates, we prove that the problems possess solution in Hardy class, the solution w(z) belongs to
, p>2.
