On certain classes of $p$-valent functions [PDF]

open access: yesČasopis pro pěstování matematiky, 1988
Let \(K^*_{n+p-1}\) be a class of p-valent functions of the form \(f(z)=z^ p-\sum^{\infty}_{k=1}a_{p+k}z^{p+k},\) \(a_{p+k}\geq 0\), for \(k=1,2,...\), and such that \(Re(D^{n+p}f(z)/D^{n+p-1}f(z))>\) for \(| z|

On strong starlikeness criteria of $p$-valent functions [PDF]

open access: yesMathematica Bohemica, 2008
Summary: \textit{H. Silverman} [Int. J. Math. Sci. 22, 75--79 (1999; Zbl 0921.30009)] investigated the properties of functions defined in terms of the quotient of the analytic representations of convex and starlike functions. Many research workers have been working on analytic functions to be strongly starlike like \textit{M.

Inclusion and properties neighbourhood for certain p-valent functions associated with complex order and q–p-valent Cătaş operator

open access: yesJournal of Taibah University for Science, 2020
Here in our paper, we present two new subclasses of multivalent analytic functions and complex order by using q–p-valent Cătaş operator. Also we obtain coefficient estimates and consequent inclusion relationships involving the $N_{i,\delta }^{\mathbf {p}

Certain Results on Fuzzy p-Valent Functions Involving the Linear Operator

open access: yesMathematics, 2023
The idea of fuzzy differential subordination is a generalisation of the traditional idea of differential subordination that evolved in recent years as a result of incorporating the idea of fuzzy set into the field of geometric function theory.
