A new characterization of right keys, and the -symmetric Schur functions at
Luc Lapointe, Luis Pena
The ring of -symmetric functions consists of the formal power series that are symmetric in the variables but carry no symmetry in the first var…
Observational Constraints on Kazakov-Solodukhin Quantum-Deformed Black Holes from M87 and Sgr A Shadows
A. Errehymy, Y. Khedif, M. Daoud +4
We explore the Kazakov-Solodukhin quantum-deformed black hole spacetime, characterized by a single deformation parameter \( η\) that encodes quantum corrections to the classical S…
Slowly rotating traversable wormholes supported by radially varying string-fluid matter: From regular geometries to photon trajectories
A. Errehymy, B. Turimov, M. A. Khan +3
This work investigates slowly rotating traversable wormholes supported by string fluids whose properties vary with distance from the throat. This radial variation allows the matter…
Dymnikova-Schwinger quantum-corrected slowly rotating wormholes: Photon and spinning particle dynamics
A. Errehymy, Y. Khedif, M. Daoud +3
This work studies light propagation near slowly rotating traversable wormholes supported by a quantum-inspired matter source. The model is based on the Dymnikova density profile, v…
Dark Energy Stars in Rastall-Rainbow Gravity: Structure, Stability and Observational Constraints
Ayan Banerjee, Bobur Turimov, Sulton Usanov +3
In this work, we investigate static configurations of dark energy stars within the framework of Rastall-Rainbow (R-R) gravity, which combines an energy-dependent deformation of spa…
Particles acceleration by Bocharova-Bronnikov-Melnikov-Bekenstein black hole
Bobur Turimov, Sulton Usanov, Yokubjon Khamroev
We have studied the motion of massive particles under the influence of scalar and gravitational fields, with particular emphasis on the BBMB black hole. It has been shown that the…
