More on entropy function formalism for non-extremal branes
Mohammad R. Garousi, Ahmad Ghodsi, Tooraj Houri +1
We find R^4 correction to the non-extremal D1D5P solution of the supergravity by exactly solving the differential equations of motion and by using the entropy function formalism. I…
Strong Gaussian approximations of product-limit and Quantile Processes for Strong mixing and censored data
V. Fakoor, N. Nakhaee Rad
In this paper, we consider the product-limit quantile estimator of an unknown quantile function under a censored dependent model. This is a parallel problem to the estimation of th…
A characterization of Hilbert -modules over finite dimensional -algebras
Lj. Arambasic, D. Bakic, M. S. Moslehian
We show that the unit ball of a full Hilbert -module is sequentially compact in a certain weak topology if and only if the underlying -algebra is finite dimensional. This…
An operator extension of Bohr's inequality
M. S. Moslehian, J. Pecaric, I. Peric
We establish an operator extension of the following generalization of Bohr's inequality, due to M.P. Vasić and D.J. Kečkić: $$|\sum_{i=1}^n z_i|^r \leq (\sum_{i=1}^n α_i^{1/(1-r)})…
Tachyon Couplings to Fermion
Mohammad R. Garousi
By fixing the internal CP factor of tachyon and massless Ramond vertex operators in different pictures, we have shown that the internal CP factor of the disk level S-matrix element…
On modified tachyon DBI action
Mohammad R. Garousi
Recently a modification of the tachyon DBI action has been proposed in which the tachyon carries the internal CP matrix σ_1 and σ_2. In this paper, we find the momentum expansion o…
Operator extensions of Hua's inequality
Mohammad Sal Moslehian
We give an extension of Hua's inequality in pre-Hilbert -modules without using convexity or the classical Hua's inequality. As a consequence, some known and new generalization…
On non-linear action of multiple M2-branes
Mohammad R. Garousi
A nonlinear SO(8) invariant BF type Lagrangian for describing the dynamics of N M2-branes in flat spacetime has been proposed recently in the literature which is an extension of th…
A proposal for M2-brane-anti-M2-brane action
Mohammad R. Garousi
We propose a manifestly SO(8) invariant BF type Lagrangian for describing the dynamics of M2-brane-anti-M2-brane system in flat spacetime. When one of the scalars which satisfies a…
On thermodynamics of N=6 superconformal Chern-Simons theories at strong coupling
Mohammad R. Garousi, Ahmad Ghodsi, Mehran Khosravi
Recently it has been conjectured that N=6, U(N)_{k} \times U(N)_{-k} Chern-Simons theory is dual to M-theory on AdS_4\times S^7/Z_{k}. By studying one-loop correction to the M-theo…
Hot accretion with outflow and thermal conduction
Mohsen Shadmehri
We present self-similar solutions for advection -dominated accretion flows with thermal conduction in the presence of outflows. Possible effects of outflows on the accretion flow a…
Hydrodynamics of N=6 Superconformal Chern-Simons Theories at Strong Coupling
Mohammad R. Garousi, Ahmad Ghodsi
Using the duality conjecture between N=6 supersymmetric U(N)_k \times U(N)_{-k} Chern-Simons theory and M-theory on AdS_4 \times S^7/Z_{k}, we calculate the corrections to the shea…

Davod Khojasteh Salkuyeh, Faezeh Toutounian
In this paper, a method via sparse-sparse iteration for computing a sparse incomplete factorization of the inverse of a symmetric positive definite matrix is proposed. The resultin…
Improved model for the topological soliton-potential interaction in Phi^4 Model
Ensieh Hakimi, Kurosh Javidan
An improved model for the soliton-potential interaction is presented. This model is constructed with a better approximation for adding the potential to the lagrangian through a spa…
Reanalysis of two eclipsing binaries: EE Aqr and Z Vul
Sayyed Mohammad Reza Ghoreyshi, Jamshid Ghanbari, Fatemeh Salehi
We study the radial-velocity and light curves of the two eclipsing binaries EE Aqr and Z Vul. Using the latest version of the Wilson & Van Hamme (2003) model, absolute parameters f…
The Effects of Thermal Conduction on the ADAF with a Toroidal Magnetic Field
S. Abbassi, J. Ghanbari, S. Najjar
The observation of the hot gas surrounding Sgr and a few other nearby galactic nuclei imply that electron and proton mean free paths are comparable to the gas capture radius.…
Analytical formulation for soliton-potential dynamics
Kurosh Javidan
An analytical model for the soliton-potential interaction is presented, by constructing a collective coordinate for the system. Most of the characters of the interaction are derive…
An Accretion-Disc Model for the Algol-Type Eclipsing Binary System AV Del
Sayyed Mohammad Reza Ghoreyshi, Jamshid Ghanbari, Fatemeh Salehi
This study inspects the light and radial-velocity curves of the eclipsing binary AV Del. In comparison with other studies already done, the study shows that the absolute elements,…
The role of Kelvin-Helmholtz instability in dusty and partially ionized outflows
Mohsen Shadmehri, Turlough P. Downes
We investigate the linear theory of Kelvin-Helmholtz instability at the interface between a partially ionized dusty outflow and the ambient material analytically. We model the inte…

Let $\A$ be a -algebra and $\B$ be a von Neumann algebra that both act on a Hilbert space $\Ha$. Let $\M$ and be inner product modules over $\A$ and $\B$, respectively. U…
