By using generalized Salagean differential operator a new<br />class of univalent holomorphic functions with fixed finitely many<br />coefficients is defined. Coefficient estimates, extreme points,<br />arithmetic mean, and weighted mean properties are investigated.

In this paper we study the module contractibility of<br />Banach algebras and characterize them in terms the concepts<br />splitting and admissibility of short exact sequences. Also we<br />investigate module contractibility of Banach algebras with the<br />concept of the module diagonal.

The goal of this paper is to investigate the solution<br />and stability in random normed spaces, in non--Archimedean spaces<br />and also in $p$--Banach spaces and finally the stability using the<br />alternative fixed point of generalized additive functions in<br />several variables.

Comments on relaxed $(gamma, r)$-cocoercive mappings

We show that the variational inequality $VI(C,A)$ has a<br />unique solution for a relaxed $(gamma , r)$-cocoercive,<br />$mu$-Lipschitzian mapping $A: Cto H$ with $r>gamma mu^2$, where<br />$C$ is a nonempty closed convex subset of a Hilbert space $H$. From<br />this result, it can be derived that, for example, the recent<br />algorithms given in the references of this paper, despite their<br />becoming more complicated, are not general as they should be.

The notion of a probabilistic metric space corresponds to the<br />situations when we do not know exactly the<br /> distance. Probabilistic Metric space was<br /> introduced by Karl Menger. Alsina, Schweizer and Sklar gave a general definition of<br /> probabilistic normed space based on the definition of Menger [1]. In this note we study the PN spaces which are<br /> topological vector spaces and the open mapping and closed graph<br /> Theorems in this spaces are proved.
