Let S denote the class of functions f(z) which are analytic in the unit disc D={z:|z|<1} and normalized by the conditions f(0)=0=f′(0)-1. Let K(μ)and S (m,M ) be the subclasses of S and satisfying the conditions 相似文献

在中学代数里我们学过复数,我们知道,复数可用平面上的向量或点来表示,利用复数的基本运算及其几何意义,已经解决了许多平面几何问题.本文对此不作详细介绍,而限于讨论怎样用复数表达一个三角形 相似文献

In this paper we introduce and study some new subclasses of meromorphic starlike multivalentfunctions.Inclusion relations are established,Integral transforms of functions in these classes are alsoconsidered.In particular,our results include or improve several results due to Mogra et al.[2],Mogra[3],Goel and Sohe[4]and Bajpai[5]. 相似文献

本文沿用文献[1]的定义,记号批语.Srivastava和Owa在[1]中引进了单位圆盘U={z:|z|<1}内解析函数类B~a和C~a(0≤a<1),对这两类函数的分数次积分与分数次导数建立了三个定理,即定理8,定理9,与定理10(见[1,pp.223-228]).他们断言:除估计式(4.15)和(4.16)不准确外,所得结果皆准确,其极值函数分别由(4.12),(4.21)与(4.30)确定. 相似文献

In this note we shall use the same notations and terms as ones in[1,3].Very recently,Sarangi and Patil[1]if considered the subclass P_k(p,A,B)of analyticp-valent functions with negative and missing coefficients and proved seven theorems con-cerning the class P_k(p,A,B).Theorems1,2,3,5,6 and7 of[l]generalize the correspondingresults obtained by Goel and Sohi[2]from k=1 to k≥2.However,it is easy to see thatsuch a generalization is trivial and simple. 相似文献

某些P叶函数的Hadamard乘积 总被引:1,自引:0,他引:1
在这里及以后凡是出现的 P 总指正整数,n 均为大于-P 的整数.类 L(n+p-1)非空,例如2~p∈L(n+p-1).鉴于(1.2),条件(1.3)改写成 Re(D~(n+p)f(z))/D_(n+p-1)f(z))>(n+p-1)/(n+p),z∈E.本文得出了与类 K_(n+p-1)。有关的一个定理,而着重研究的是类 L_(n+p-1)的某些卷积性质.作为特殊情形,我们的工作(推论2.2,2.3,推论3.1~3.6以及推论3.7~3.9)改进与推广了R.J.Libera[3].S.D.Bernardi[4,5]的主要结果. 相似文献
