2 - A new type of Hyers-Ulam-Rassias stability for Drygas functional equation
M. Sirouni M. ‎Almahalebi S. ‎KabbajIn this paper, we prove the generalized Hyers-Ulam-Rassias stability for the Drygas functional equation$$f(x+y)+f(x-y)=2f(x)+f(y)+f(-y)$$ in Banach spaces by using the Brz\c{d}ek's fixed point theorem. Moreover, we give a general result on the hyperstability of this equ چکیده کاملIn this paper, we prove the generalized Hyers-Ulam-Rassias stability for the Drygas functional equation$$f(x+y)+f(x-y)=2f(x)+f(y)+f(-y)$$ in Banach spaces by using the Brz\c{d}ek's fixed point theorem. Moreover, we give a general result on the hyperstability of this equation. Our results are improvements and generalizations of the main result of M. Piszczek and J. Szczawi\'{n}ska [21]. پرونده مقاله -

3 - Steffensen method for solving nonlinear matrix equation $X+A^T X^{(-1)}A=Q$
A. Nazari Kh. Sayehvand M. RostamiIn this article we study Steffensen method to solve nonlinear matrix equation $X+A^T X^{(-1)}A=Q$,when $A$ is a normal matrix. We establish some conditionsthat generate a sequence of positive definite matrices which converges to solutionof this equation.In this article we study Steffensen method to solve nonlinear matrix equation $X+A^T X^{(-1)}A=Q$,when $A$ is a normal matrix.
