Abstract
In the present paper we study certain subclasses Hλ,μ,η(a,b,pσ) and Kλ,μ,η(a,b,pσ) of analytic and p-valent functions. The results presented include coefficient estimates and distorsion properties for functions belonging to such classes. Further results giving closure theorems, various properties and modified Hadamard products of several functions belonging to above classes are also mentioned.
Keywords
Analytic and p-valent functions; fractional derivative operator; Riemann-Liouville and Erdelyi-Kober operators; Hadamard products
