用Ruscheweyh导数刻画的解析函数新子类

摘要

引进并研究用Ruscheweyh导数定义的解析函数类Sk,[λα,β,ρ].结合算子理论导出类中函数的积分表达式、偏差定理,讨论类中函数的半径问题和Hadamard卷积性质.%A class of analytical functions Sk,x （a,fl,p） defined by making use of Ruscheweyh derivatives is introduced and studied. We provide integral representations, distortiontheorem, and discuss the radius problem and Hadamard product properties.
