On Permutation Binomials over Finite Fields
Mohamed Ayad, Belghaba Kacem, Omar Kihel
Let be the finite field of characteristic containing elements and a binomial with coefficients in this field. If some conditi…
Exponentials of Bounded Normal Operators
Aicha Chaban, Mohammed Hichem Mortad
The present paper is mainly concerned with equations involving exponentials of bounded normal operators. Conditions implying commutativity of those normal operators are given. This…
Exponentials of Normal Operators and Commutativity of Operators: A New Approach
Mohammed Hichem Mortad
We present a new approach to the question of when the commutativity of operator exponentials implies that of the operators. This is proved in the setting of bounded normal operator…
Coulomb-Gas Approach For Percolation Theory
Smain Balaska, Toufik Sahabi
The aim of this work is to present a non trivial confirmation of the powerful of the Coulomb gas-techniques for Boundary Conformal Field Theory (BCFT). We show that we can re-deriv…
Growth of silicene layers on Ag(111): unexpected effect of the substrate temperature
H. Jamgotchian, Y. Colignon, N. Hamzaoui +4
The deposition of one silicon monolayer on the silver (111) substrate in the temperature range 150-300C, gives rise to a mix of (44), ()R…
Bayesian sequential estimation of the reliability of a parallel-series system
Zohra Benkamra, Mekki Terbeche, Mounir Tlemcani
We give a risk-averse solution to the problem of estimating the reliability of a parallel-series system. We adopt a beta-binomial model for components reliabilities, and assume tha…
