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.

Vaccination against Streptococcus pneumoniae in Children Born between 2015 and 2018 in Poland—How Has the Introduction of Free Compulsory Pneumococcal Vaccination Affected Its Uptake?

open access: yesVaccines, 2023
Starting from 2017, pneumococcal vaccination was added to the Polish vaccination calendar as mandatory for all children born after 2016. The 10-valent conjugate vaccine was selected as mandatory and therefore free of charge.

ON CERTAIN MEROMORPHIC P-VALENT FUNCTIONS

open access: yesTaiwanese Journal of Mathematics, 1998
Summary: A certain differential operator \(D^n\) is introduced for functions of the form \(f(z)={1\over z^p}+\sum^\infty_{k=0}a_kz^k\) which are analytic in \(E^*=\{z ...

Faecal haemoglobin can define risk of colorectal neoplasia at surveillance colonoscopy in patients at increased risk of colorectal cancer. [PDF]

open access: yes, 2020
Background: Quantitative faecal immunochemical tests measure faecal haemoglobin concentration (f-Hb), which increases in the presence of colorectal neoplasia.Objective: We examined the diagnostic accuracy of faecal immunochemical test (FIT)in patients at

On certain classes of p-Valent functions by using complex-order and differential subordination. [PDF]

open access: yes, 2010
The aim of the present paper is to study the p-valent analytic functions in the unit disk and satisfy the differential subordinations z(Ip)r, ?(f(z))(j+1)/(p - j)(?p(r, ?)f(z))(j) < (a + (aB + (A- B)ß)z)/a(1 + Bz), where ?p(r, ?) is an operator defined ...

Generalizations of p-valent functions via the hadamard product

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
The classes of univalent prestarlike functions Rα, α≥−1, of Ruscheweyh [1] and a certain generalization of Rα were studied recently by Al-Amiri [2]. The author studies, among other things, the classes of p-valent functions R(α+p−1) where p is a positive ...
