Weyl collineations that are not curvature collineations
Ibrar Hussain, Asghar Qadir, K. Saifullah
Though the Weyl tensor is a linear combination of the curvature tensor, Ricci tensor and Ricci scalar, it does not have all and only the Lie symmetries of these tensors since it is…
Quantum Trajectory Analysis of the Two-Mode Three-Level Atom Microlaser
Tarek A. Elsayed, Abdulaziz Aljalal
We consider a single atom laser (microlaser) operating on three-level atoms interacting with a two-mode cavity. The quantum statistical properties of the cavity field at steady sta…
t-Class semigroups of Noetherian domains
S. Kabbaj, A. Mimouni
The t-class semigroup of an integral domain is the semigroup of fractional t-ideals modulo its subsemigroup of nonzero principal ideals with the operation induced by ideal t-multip…
Commutative rings in which every finitely generated ideal is quasi-projective
J. Abuhlail, M. Jarrar, S. Kabbaj
This paper studies the multiplicative ideal structure of commutative rings in which every finitely generated ideal is quasi-projective. Section 2 provides some preliminaries on qua…
Trivial extensions defined by Prufer conditions
C. Bakkari, S. Kabbaj, N. Mahdou
This paper deals with well-known extensions of the Prufer domain concept to arbitrary commutative rings. We investigate the transfer of these notions in trivial ring extensions (al…
