The Atkinson Theorem in Hilbert C*-Modules Over C*-Algebras of Compact Operators
Assadollah Niknam, Kamran Sharifi
In this paper the concept of unbounded Fredholm operators on Hilbert C*- modules over an arbitrary C*-algebra is discussed and the Atkinson theorem is generalized for bounded and u…
On Automatic Continuity of 3-Homomorphisms on Banach Algebras
Janko Bracic, Mohammad Sal Moslehian
A linear map between (Banach) algebras is called 3-homomorphism if for each . We investigate 3-hom…
Superstring Scattering from O-planes
Mohammad R. Garousi
We write the vertex operators of massless NS-NS and RR states of Type II superstring theory in the presence of Orientifold p-planes. They include the usual vertex operators of Type…
Diquark Approach to Calculating the Mass and Stability of H - Dibaryon
Alireza Haghpayma
By using of vector diquark ideas in the chiral limit diquark correlations in the relativistic region and imposing HF interactions between quarks in a vector diquark we calculated t…
Magnetic Moment of the Pentaquark THETA+ State
A. R. Haghpayma
We consider THETA+ pentaquark as a bound state of two vector diquarks and one anti-quark and calculate its magnetic moment.
Self-Similar Evolutionary Solutions of Self-Gravitating, Polytropic -Viscous Disks
Shahram Abbassi, Jamshid Ghanbari, Fatemeh Salehi
We carry out the effect of -prescription for viscosity which introduced by Duschel et al. 2000 & Hure, Richard & Zhan 2001, in a standard self-gravitating thin disks. We were pr…
Non-abelian expansion of S-matrix elements and non-abelian tachyon DBI action
Kazem Bitaghsir-Fadafan, Mohammad R. Garousi
We apply the prescription proposed in hep-th/0307197 for non-abelian expansion of S-matrix elements, to the S-matrix element of four tachyons and one gauge field in superstring the…
The Virial Balance of Clumps and Cores in Molecular Clouds
Sami Dib, Jongsoo Kim, Enrique Vazquez-Semadeni +2
We study the instantaneous virial balance of clumps and cores (CCs) in 3D simulations of driven, MHD, isothermal molecular clouds (MCs). The models represent a range of magnetic fi…
Theta pentaquark In Multiquark Theories
A. R. Haghpayma
In this paper we explain and discuss some fundamental features of various models which are QCD-based and proposed to explain the hadron spectrum.
A review of the pentaquark Theta properties
A. R. Haghpayma
Although the Theta has been listed as a three star resonance in the 2004 PDG,its existence is still not completely established. Now it is still of interest to see what QCD has to s…
Theta in a conventional correlated perturbative chiral quark model
A R. Haghpayma
In a conventional covark model we constructed the Theta pentaquark wave function using vector diquarks and calculating the mass spectrum of this exotic pentaquark.
Orthogonal Constant Mappings in Isosceles Orthogonal Spaces
M. Mirzavaziri, M. S. Moslehian
In this paper we introduce the notion of orthogonally constant mapping in an isosceles orthogonal space and establish stability of orthogonally constant mappings. As an application…
Interaction of topological solitons with defects: using a nontrivial metric
Kurosh Javidan
By including potential into the flat metric, we study interaction of sine-Gordon soliton with potentials. We will show numerically that while the soliton-barrier system shows fully…
Formation of Small-Scale Condensations in the Molecular Clouds via Thermal Instability
Mohsen Nejad-Asghar, Jamshid Ghanbari
A systematic study of the linear thermal instability of a self-gravitating magnetic molecular cloud is carried out for the case when the unperturbed background is subject to local…
