According to Godunov theorem for numerical calculations of advection equations, there exist no high-er-order schemes with constant positive difference coefficients in a family of polynomial schemes wi...
Coefficient inequalities, distortion theorems and class preserving integral operators are obtained for p-valent meromorphic starlike functions of order α (0 ≤ α < p) with negative coefficients.
A classical theorem of Landau states that, if an ordinary Dirichlet series has non-negative coefficients, then it has a singularity on the real line at its abscissae of absolute convergence.
We introduce the class of analytic functions with negative coefficients. In this paper we give some properties of functions in the class and we obtain coefficient estimates, neighborhood and integ...

Integral Means for Starlike and Convex Functions with Negative Coefficients.
On A Certain Class Of $p-$Valent Functions With Negative Coefficients.
On certain class of univalent functions with negative coefficients.
For λ ≥ 0, n N0, in [3], the authors introduced the operator Dn λ,which is a generalized Ruscheweyh derivatives operator. In this paper,some results on coefficient inequalities, growth and distortio...
Some oscillation criteria for the following second-order neutral differential equation [x(t)\pm r(t) f( x(t-g))]''+p(t) g(x(t-a)) -q(t) g(x(t-b )) = s(t) where t\geq t0, g,a,b \in R+ with a \geq b, r ...
We introduce a subclass K*n+p-1(A,B) of analytic and p-valent functions with negative coefficients. Coefficient estimates, some properties, distortion theorems and closure theorems of functions belong...
The object of the present paper is to prove various distortion theorems for the fractional calculus of functions in the class Tn\left(l,a\right) consisting of analytic and univalent functions with neg...
