  • On the irreducibility of the complex specialization of the representation of the Hecke algebra of the complex reflection group $G_7$ 

    Chreif, M. Y.؛ Abdulrahim, M. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    We consider a 2-dimensional representation of the Hecke algebra $H(G_7, u)$, where $G_7$ is the complex reflection group and $u$ is the set of indeterminates $u = (x_1,x_2,y_1,y_2,y_3,z_1,z_2,z_3)$. After specializing the ...

  • Construction of strict Lyapunov function for nonlinear parameterised perturbed systems 

    Ghanmi, B.؛ Hammami, M. A. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    In this paper, global uniform exponential stability of perturbed dynamical systems is studied by using Lyapunov techniques. The system presents a perturbation term which is bounded by an integrable function with the ...

  • On the commuting graph of some non-commutative rings with unity 

    Ramezani, F.؛ Vatandoost, E. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    ‎‎Let $R$ be a non-commutative ring with unity‎. ‎The commuting graph‎ of $R$ denoted by $Gamma(R)$‎, ‎is a graph with a vertex set‎ ‎$Rsetminus Z(R)$ and two vertices $a$ and $b$ are adjacent if and only if‎ $ab=ba$‎. ‎In ...

  • Preorder Relators and Generalized Topologies 

    Arianpoor, H. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    In this paper we investigate generalized topologies generated by a subbase of preorder relators and consider its application in the concept of the complement. We introduce the notion of principal generalized topologies ...

  • On quasi-baer modules 

    Shafiee-Mousavi, M. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    Let $R$ be a ring, $sigma$ be an endomorphism of $R$ and $M_R$ be a $sigma$-rigid module. A module $M_R$ is called quasi-Baer if the right annihilator of a principal submodule of $R$ is generated by an idempotent. It is ...

  • Connected and Hyperconnected Generalized Topological Spaces 

    Basdouri, I.؛ Messaoud, R.؛ Missaoui, A. (Central Tehran Branch, Islamic Azad University, 2016-12-01)
    A. Csaszar introduced and extensively studied the notion of generalized open sets. Following Csazar, we introduce a new notion hyperconnected. We study some speci c properties about connected and hyperconnected in generalized ...
