A simple proof of a theorem on (2n)-weak amenability
M. S. Moslehian, F. Negahban
A simple proof of (2n)-weak amenability of the triangular Banach algebra T= [(A A) (0 A)] is given where A is a unital C*-algebra.
Excited D-brane decay in Cubic String Field Theory and in Bosonic String Theory
M. R. Garousi, G. R. Maktabdaran
In the cubic string field theory, using the gauge invariant operators corresponding to the on-shell closed string vertex operators, we have explicitly evaluated the decay amplitude…
Constraints on Star Formation from the Close Packing of Protostars in Clusters
Bruce G. Elmegreen, Mohsen Shadmehri
The mm-wave continuum sources (MCS) in Ophiuchus have mutual collision rates less than their collapse rates by a factor of 10 to 100, suggesting most will form stars without furthe…
On-shell S-matrix and tachyonic effective actions
Mohammad R. Garousi
We evaluate various disk level four-point functions involving the massless scalar and tachyon vertex operators in the presence of background B-flux in superstring theory. By studyi…
Berry's phase in noncommutative spaces
S. A. Alavi
We introduce the perturbative aspects of noncommutative quantum mechanics. Then we study the Berry's phase in the framework of noncommutative quantum mechanics. The results show de…
Can Hydrostatic Cores Form Within Isothermal Molecular Clouds?
Enrique Vazquez-Semadeni, Mohsen Shadmehri, Javier Ballesteros-Paredes
Under the assumptions that molecular clouds are nearly spatially and temporally isothermal and that the density peaks (``cores'') within them are formed by turbulent fluctuations,…
Gravity on Noncommutative D-Branes
F. Ardalan, H. Arfaei, M. R. Garousi +1
The effective action for the low energy scattering of two gravitons with a D-brane in the presence of a constant antisytmetric field in bosonic string theory is calculated and…
Gauge Invariant Operators and Closed String Scattering in Open String Field Theory
Mohsen Alishahiha, Mohammad R. Garousi
Using the recent proposal for the observables in open string field theory, we explicitly compute the coupling of closed string tachyon and massless states with the open string stat…
