Tate cohomology with respect to semidualizing modules
Sean Sather-Wagstaff, Tirdad Sharif, Diana White
We investigate Tate cohomology of modules over a commutative noetherian ring with respect to semidualizing modules. We identify classes of modules admitting Tate resolutions and an…
Scaling Relations for Contour Lines of Rough Surfaces
M. A. Rajabpour, S. M. Vaez Allaei
Equilibrium and non-equilibrium growth phenomena, e.g., surface growth, generically yields self-affine distributions. Analysis of statistical properties of these distributions appe…
Zipping and Unzipping of Cosmic String Loops in Collision
Hassan Firouzjahi, Johanna Karouby, Shahram Khosravi +1
In this paper the collision of two cosmic string loops is studied. After collision junctions are formed and the loops are entangled. We show that after their formation the junction…
Constraints on the masses of fourth generation quarks
S. Hosseini, M. Mohammadi Najafabadi, A. Moshaii +2
We study the one-loop contribution of the down-type quark of the standard model-like fourth generation (b') on the top quark electric dipole moment. Using the known limits on the t…
Thermal Behavior of Spin Clusters and Interfaces in two-dimensional Ising Model on Square Lattice
A. A. Saberi
Extensive Monte Carlo study of two-dimensional Ising model is done to investigate the statistical behavior of spin clusters and interfaces as a function of temperature, . We use…
3-Form Flux Compactification of Salam-Sezgin Supergravity
Hamid Reza Afshar, Shahrokh Parvizi
The compactification of 6 dimensional Salam-Sezgin model in the presence of 3-form flux H is investigated. We find a torus topology for this compactification with two cusps which a…
