We say a functional equation () is stable if any function g satisfying the equation () approximately<br />is near to true solution of (). Using xed point methods, we investigate approximately higher<br />ternary derivations in Banach ternary algebras via the Cauchy functional equation<br />f(1x + 2y + 3z) = 1f(x) + 2f(y) + 3f(z) :

Acikgoz
This paper presents the following new denition which is a natural combination of the denition for<br />asymptotically double equivalent, double statistically limit and double 2 sequences. The double<br />sequence 2 = (m;n) of positive real numbers tending to innity such that<br />m+1;n m;n + 1; m;n+1 m;n + 1;<br />m;n m+1;n m;n+1 m+1;n+1; 1;1 = 1;<br />and<br />Im;n = f(k; l) : m m;n + 1 k m; n m;n + 1 l ng :<br />For double 2sequence; the two non-negative sequences x = (xk;l) and y = (yk;l) are said to be<br />2asymptotically double statistical equivalent of multiple L provided that for every " > 0<br />P lim<br />m;n<br />1<br />m;n<br /><br /><br />(k; l) 2 Im;n :<br /><br />xk;l<br />yk;l<br /> L<br /><br /> "<br /><br />= 0<br />(denoted by x<br />SL<br />2 v y) and simply 2asymptotically double statistical equivalent if L = 1.

Belarbi
In this paper, we study the existence of solutions for fractional evolution equations with nonlocal<br />conditions. These results are obtained using Banach contraction xed point theorem. Other results<br />are also presented using Krasnoselskii theorem.

On invariant sets topology
M.
Eshaghi Gordji
M.
Rostamian Delavar
In this paper, we introduce and study a new topology related to a self mapping on a nonempty set.<br />Let X be a nonempty set and let f be a self mapping on X. Then the set of all invariant subsets of<br />X related to f, i.e. f := fA X : f(A) Ag P(X) is a topology on X. Among other things,<br />we nd the smallest open sets contains a point x 2 X. Moreover, we find the relations between f<br />and To f . For instance, we find the conditions on f to show that whenever f is T0, T1 or T2.

Weights in block iterative methods
T.
Nikazad
M.
Abbasi
In this paper we introduce a sequential block iterative method and its simultaneous version with op-<br />timal combination of weights (instead of convex combination) for solving convex feasibility problems.<br />When the intersection of the given family of convex sets is nonempty, it is shown that any sequence<br />generated by the given algorithms converges to a feasible point. Additionally for linear feasibility<br />problems, we give equivalency of our algorithms with sequential and simultaneous block Kaczmarz<br />methods explaining the optimal weights have been inherently used in Kaczmarz methods. In addi-<br />tion, a convergence result is presented for simultaneous block Kaczmarz for the case of inconsistent<br />linear system of equations.

Fixed points for Banach and Kannan contractions in modular spaces with a graph
A.
Aghanians
K.
Nourouzi
In this paper, we discuss the existence and uniqueness of xed points for Banach and Kannan<br />contractions dened on modular spaces endowed with a graph. We do not impose the Δ2-condition<br />or the Fatou property on the modular spaces to give generalizations of some recent results. The<br />given results play as a modular version of metric xed point results.

Sharing several secrets based on Lagrange's interpolation formula and Cipher feedback mode
A.
Cheraghi
In a multi-secret sharing scheme, several secret values are distributed among a set of n participants.<br />In 2000 Chien et al.'s proposed a (t; n) multi-secret sharing scheme. Many storages and public<br />values required in Chien's scheme. Motivated by these concerns, some new (t; n) multi-secret sharing<br />schemes are proposed in this paper based on the Lagrange interpolation formula for polynomials and<br />cipher feedback mode (CFB), which are easier than Chien's scheme in the secret reconstruction and<br />require fewer number of public values and storages than Chien's scheme. Also our schemes don't<br />need any one-way function and any simultaneous equations.

An equivalent representation for weighted supremum norm on the upper half-plane
M.A.
Ardalani
In this paper, rstly, we obtain some inequalities which estimates complex polynomials on the circles.<br />Then, we use these estimates and a Moebius transformation to obtain the dual of this estimates for<br />the lines in upper half-plane. Finally, for an increasing weight on the upper half-plane with<br />certain properties and holomorphic functions f on the upper half-plane we obtain an equivalent<br />representation for weighted supremum norm.

New results on the quasi-commuting inverses
M.
Nikuie
A.
Zohri
M.K.
Mirnia
A matrix has an ordinary inverse only if it is square, and even then only if it is nonsingular or, in<br />other words, if its columns (or rows) are linearly independent. In recent years needs have been felt in<br />numerous areas of applied mathematics for some kind of partial inverse of a matrix that is singular<br />or even rectangular. In this paper, some results on the Quasi-commuting inverses, are given and<br />the eect of them in solving the case of linear system of equations where the coecient matrix is a<br />singular matrix, is illustrated.

Bhaskar-Lakshmikantham type results for monotone mappings in partially ordered metric spaces
S.
Radenovic
In this paper, coupled xed point results of Bhaskar-Lakshmikantham type [T. Gnana Bhaskar, V.<br />Lakshmikantham, Fixed point theorems in partially ordered metric spaces and applications, Nonlinear<br />Analysis 65 (2006) 1379-1393] are extend, generalized, unify and improved by using monotone<br />mappings instead mappings with mixed monotone property. Also, an example is given to support<br />these improvements.
