Constraining Cosmological Parameters From Statistical Superluminal Effects Without a Distance Ladder
Hichem Guergouri, Omar Nemoul, Jamal Mimouni
We employ a statistical approach to study apparent superluminal motion of luminous sources in an expanding flat Friedmann--Lemaître--Robertson--Walker universe, explicitly incorpor…

Volume and Boundary Face Area of a Regular Tetrahedron in a Constant Curvature Space
Omar Nemoul, Noureddine Mebarki
An example of the volume and boundary face area of a curved polyhedron for the case of regular spherical and hyperbolic tetrahedron is discussed. An exact formula is explicitly der…

A Curvature Operator for a Regular Tetrahedron Shape in LQG
Omar Nemoul, Noureddine Mebarki
An alternative approach introducing a 3 dimensional Ricci scalar curvature quantum operator given in terms of volume and area as well as new edge length operators is proposed. An e…
