Applications of Mittag–Leffler Functions on a Subclass of Meromorphic Functions Influenced by the Definition of a Non-Newtonian Derivative

Fractal and Fractional
In this paper, we defined a new family of meromorphic functions whose analytic characterization was motivated by the definition of the multiplicative derivative.

Certain classes of meromorphically P-valent starlike functions

Applied Mathematics Letters, 1994
Let \(\sum_ p\) denote the class of functions \(f(z) = \sum^ \infty_{k = - p} a_{k + p - 1} z^ k\) with \((a_{-1}=1)\) which are analytic for ...

On a certain subclass of meromorphic univalent functions with fixed second positive coefficients [PDF]

, 2010
In the present paper, we consider the subclass of meromorphic univalent functions Sp*[k,α,β,c] with fixed second positive coefficient. The object of the present paper is to show coefficient estimates, onvex liner combinations, some distortion theorems ...

Hadamard Product on Subclasses of Meromorphic Functions Involving q-Difference Operator

Journal of Function Spaces
By making use of a q-derivative operator, certain families of meromorphic q-starlike functions and meromorphic q-convex functions are introduced and studied. In this paper, we define a q-analogous value of differential operators for meromorphic functions

Starlikeness of General Integral Operator for Meromorphic Multivalent Functions [PDF]

Journal of Complex Analysis, 2013
We introduce a new integral operator for meromorphic multivalent functions. The starlikeness condition of this integral operator is determined. Several special cases are also discussed in the form of corollaries.

Some properties and results for certain subclasses of starlike and convex functions [PDF]

Sahand Communications in Mathematical Analysis, 2017
In the present paper, we introduce and investigate some properties of two subclasses $ Lambda_{n}( lambda , beta ) $ and $ Lambda_{n}^{+}( lambda , beta ) $;  meromorphic and starlike  functions of order $ beta $.

Coefficient inequalities for concave and meromorphically starlike univalent functions [PDF]

Annales Polonici Mathematici, 2008
Let $\ID$ denote the open unit disk and $f:\,\ID\TO\BAR\IC$ be meromorphic and univalent in $\ID$ with the simple pole at $p\in (0,1)$ and satisfying the standard normalization $f(0)=f'(0)-1=0$. Also, let $f$ have the expansion $$f(z)=\sum_{n=-1}^{\infty}a_n(z-p)^n,\quad |z-p|<1-p, $$ such that $f$ maps $\ID$ onto a domain whose complement with ...
