[ 1 ] - Dynamic system of strategic games
Maybe an event can't be modeled completely through one game but there is more chance with several games. With emphasis on players' rationality, we present new properties of strategic games, which result in production of other games. Here, a new attitude to modeling will be presented in game theory as dynamic system of strategic games and its some applications such as analysis of the clash betwe...
[ 2 ] - Statistical uniform convergence in $2$-normed spaces
The concept of statistical convergence in $2$-normed spaces for double sequence was introduced in [S. Sarabadan and S. Talebi, {it Statistical convergence of double sequences in $2$-normed spaces }, Int. J. Contemp. Math. Sci. 6 (2011) 373--380]. In the first, we introduce concept strongly statistical convergence in $2$-normed spaces and generalize some results. Moreover, we define the conce...
[ 3 ] - An inequality related to $eta$-convex functions (II)
Using the notion of eta-convex functions as generalization of convex functions, we estimate the difference between the middle and right terms in Hermite-Hadamard-Fejer inequality for differentiable mappings. Also as an application we give an error estimate for midpoint formula.
[ 4 ] - Stability and hyperstability of orthogonally ring $*$-$n$-derivations and orthogonally ring $*$-$n$-homomorphisms on $C^*$-algebras
In this paper, we investigate the generalized Hyers-Ulam-Rassias and the Isac and Rassias-type stability of the conditional of orthogonally ring $*$-$n$-derivation and orthogonally ring $*$-$n$-homomorphism on $C^*$-algebras. As a consequence of this, we prove the hyperstability of orthogonally ring $*$-$n$-derivation and orthogonally ring $*$-$n$-homomorphism on $C^*$-algebras.
[ 5 ] - مدلسازی توزیع بودجه در ایران با استفاده از نظریه بازی‌ها
مسائل و مشکلات موجود در امر بودجه‌ریزی در ایران بیش از آنکه از سیاست‌های دولت ناشی شود، به دلیل فرآیندهای سنتی در امر تهیه، تصویب و اجرای بودجه می‌باشد. هدف از این مقاله ارائه مدلی جهت توزیع و بهینه‌سازی تخصیص اعتبارات تملک دارایی‌های سرمایه‌ای استانی بین استان‌های کشور می‌باشد. بدین منظور از روش‌های نظریه بازی‌ها برای محاسبه هزینه‌ها و توزیع بودجه استفاده شده است. محدوده این تحقیق بطور اختصاصی...
[ 6 ] - Fixed Point Theory in $varepsilon$-connected Orthogonal Metric Space
The existence of fixed point in orthogonal metric spaces has been initiated by Eshaghi and et. al [7]. In this paper, we prove existence and uniqueness theorem of fixed point for mappings on $varepsilon$-connected orthogonal metric space. As a consequence of this, we obtain the existence and uniqueness of fixed point for analytic function of one complex variable. The paper concludes with some i...
[ 7 ] - The Sugeno fuzzy integral of concave functions
The fuzzy integrals are a kind of fuzzy measures acting on fuzzy sets. They can be viewed as an average membershipvalue of fuzzy sets. The value of the fuzzy integral in a decision making environment where uncertainty is presenthas been well established. Most of the integral inequalities studied in the fuzzy integration context normally considerconditions such as monotonicity or comonotonicity....
[ 8 ] - مدلسازی سوءاستفادة برخی پزشکان از اعتماد بیمار با استفاده از زنجیرة مارکوف و راهبرد ZD
در مطالعة پیش‌رو، سوءاستفادة برخی پزشکان از اعتماد بیماران خود برای به‌دست‌آوردن منافع اقتصادی بیشتر به‌کمک راهبرد دترمینان صفر و زنجیرة مارکوف بررسی شده است. هنگامی که شخصی به پزشک مراجعه می‌کند، باید به او اعتماد کند و توصیه‌هایش را جدی بگیرد؛ بنابراین اگر بیماری صعب‌العلاج باشد، راه برای سوءاستفادة بیشتر باز خواهد بود و اگر پزشک چنین هدفی را دنبال کند، برای کسب موفقیت بیشتر خود، حتی با ایجاد...
[ 9 ] - Investigation of Game Between Cells in Occurrence of Genetic Mutations Using Evolutionary Game Theory
In this paper, two games that play a role in creating a cancer tumor and suppression are studied using evolutionary game theory and its different modes are analyzed. The first game is the competition between a cancer cell and a healthy cell to receive food through the blood. In the second game, the interaction between the two oncogenes Ras and Myc is examined for cellular deformation
[ 10 ] - Evaluating the Factors Affecting on Credit Ratings of Accepted Corporates in Tehran Securities Exchange by Using Factor Analysis and AHP
Implementation credit rating for Corporates is influenced by Different circum-stances, systems, processes, and cultures in each country. In this study, we pro-posed a Factor analysis modified approach for determine important factors on real data set of 123 accepted corporate in Tehran Securities Exchange for the years 2009-2017 of diverse range of 52 variable. We estimated the priority score fo...
[ 11 ] - The dilemma of Rationality or Providing Efficiency in Monetary Policy Making: An Application of Arrow’s
Financial frictions inducted in the model is a new contribution to monetary economics. Herein, an analytical tool arranges monetary policymaking in the form of two steps procedure. In the first step, an appropriate amount of money supply should be assessed; and in the second step, that appropriate amount should be allocated to several sectors. The Central Bank obligates the step of assessment a...
