Farrokhzad M. Eshaghi We say a functional equation () is stable if any function g satisfying the equation () approximatelyis near to true solution of (). Using xed point methods, we investigate approximately higherternary derivations in Banach ternary algebras via the Cauchy functional equationf(1x + 2y + 3z) = 1f(x) + 2f(y) + 3f(z) : higher ternary derivations 2014 07 01 7 15 https://ijnaa.semnan.ac.ir/article_121_3f2a6733a98636de75a86487f4156522.pdf

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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.Let X be a nonempty set and let f be a self mapping on X. Then the set of all invariant subsets ofX related to f, i.e. f := fA  X : f(A)  Ag  P(X) is a topology on X. Among other things,we nd the smallest open sets contains a point x 2 X. Moreover, we find the relations between fand To f . For instance, we find the conditions on f to show that whenever f is T0, T1 or T2.

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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-timal combination of weights (instead of convex combination) for solving convex feasibility problems.When the intersection of the given family of convex sets is nonempty, it is shown that any sequencegenerated by the given algorithms converges to a feasible point. Additionally for linear feasibilityproblems, we give equivalency of our algorithms with sequential and simultaneous block Kaczmarzmethods explaining the optimal weights have been inherently used in Kaczmarz methods. In addi-tion, a convergence result is presented for simultaneous block Kaczmarz for the case of inconsistentlinear system of equations. 2014 07 01 37 49 https://ijnaa.semnan.ac.ir/article_125_9adafe7b3a76d7094dc7be2c82478b76.pdf

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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 Kannancontractions de ned on modular spaces endowed with a graph. We do not impose the Δ2-conditionor the Fatou property on the modular spaces to give generalizations of some recent results. Thegiven results play as a modular version of metric xed point results. 2014 07 01 50 59 https://ijnaa.semnan.ac.ir/article_126_f0449e8d71496c26173bc1b9c622400b.pdf

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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.In 2000 Chien et al.'s proposed a (t; n) multi-secret sharing scheme. Many storages and publicvalues required in Chien's scheme. Motivated by these concerns, some new (t; n) multi-secret sharingschemes are proposed in this paper based on the Lagrange interpolation formula for polynomials andcipher feedback mode (CFB), which are easier than Chien's scheme in the secret reconstruction andrequire fewer number of public values and storages than Chien's scheme. Also our schemes don'tneed any one-way function and any simultaneous equations. 2014 07 01 60 66 https://ijnaa.semnan.ac.ir/article_127_7e50439b69b888cd774502e1936b9d13.pdf

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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.Then, we use these estimates and a Moebius transformation to obtain the dual of this estimates forthe lines in upper half-plane. Finally, for an increasing weight  on the upper half-plane withcertain properties and holomorphic functions f on the upper half-plane we obtain an equivalentrepresentation for weighted supremum norm. 2014 07 01 67 79 https://ijnaa.semnan.ac.ir/article_128_293401779d9e769952a5e75f14868c3b.pdf

International Journal of Nonlinear Analysis and Applications IJNAA 2014 5 2 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, inother words, if its columns (or rows) are linearly independent. In recent years needs have been felt innumerous areas of applied mathematics for some kind of partial inverse of a matrix that is singularor even rectangular. In this paper, some results on the Quasi-commuting inverses, are given andthe e ect of them in solving the case of linear system of equations where the coecient matrix is asingular matrix, is illustrated. 2014 07 01 80 85 https://ijnaa.semnan.ac.ir/article_129_9e02585d526696dbca90a6e2bb9c5518.pdf

Gnana Bhaskar, V.Lakshmikantham, Fixed point theorems in partially ordered metric spaces and applications, NonlinearAnalysis 65 (2006) 1379-1393] are extend, generalized, unify and improved by using monotonemappings instead mappings with mixed monotone property.
