On 2d gravity and parallel transport field equation on quantum sphere
Abdelkader Yanallah
In this work we have obtained the exact quantum expressions for the compenents of the Levi Cevita connection, the Ricci tensor and the scalar curvature, generalizing those of \cite…
Weakly Charged Compact Stars in gravity
Houda Mansour, Bahia Si Lakhal, Abdelkader Yanallah
We study electrically charged compact stars in the framework of extended theory of gravity (ETG). We assume that the charge density is proportional to the energy density. The polyt…
New connection formulae for some q-orthogonal polynomials in q-Askey scheme
Abdelkader Yanallah, Mohammed Brahim Zahaf
New nonlinear connection formulae of the q-orthogonal polynomials, such continuous q-Laguerre, continuous big q-Hermite, q-Meixner-Pollaczek and q-Gegenbauer polynomials, in terms…
Addendum to "On Super-Jordanian Algebra
B. Abdesselam, A. Chakrabarti, R. Chakrabarti +2
We give a complete proof of the result (2.10) presented in our paper published in J. Phys. A: Math. Gen. 39 (2006) 8307.
On super-Jordanian algebra
B. Abdesselam, A. Chakrabarti, R. Chakrabarti +2
A nonlinear realisation of the nonstandard (super-Jordanian) deformed algebra is given for arbitrary .
Jordanian Quantum (Super)Algebras via Contraction Method and Mapping:Review
B. Abdesselam, R. Chakrabarti, A. Yanallah +1
Recently, a class of transformations of -matrices was introduced such that the limit gives explicit nonstandard -matrices. The transformation matrix is singular…
