Some classes of uniformly starlike and convex functions are introduced. The geometrical properties of these classes and their behavior under certain integral operators are investigated. 1.â€¦ (More)

By applying certain integral operators to p-valent functions we define a comprehensive family of analytic functins. The subordinations properties of this family is studied, which in certain specialâ€¦ (More)

In this paper, we establish the stability and superstability of Jâˆ—âˆ’derivations in Jâˆ—âˆ’algebras for the generalized Jensenâ€“type functional equation rf( x + y r ) + rf( x âˆ’ y r ) = 2f(x). Finally, weâ€¦ (More)

In this paper we define the function E(a, b, c, d, z) concerning hypergeometric function. The main aim of the present paper is to obtain conditions for a, b, c, d such that the functions zE(a, b, c,â€¦ (More)

where h and g are analytic in the unit disk D = {z : |z| < 1}. A sufficient coefficient condition for this function in the class HM(Î², Î», k, Î½) and a necessary and sufficient coefficient conditionâ€¦ (More)
