First-Law Entropy and a Degenerate Extremal Remnant in a Minimal-Length Simpson--Visser-Type Regular Black Hole: Geometrothermodynamics, Phase Structure, and Observational Discriminants
T. Toghrai, N. Mansour, A. Daassou +1
We construct the first-law-consistent entropy of a geometrically minimal-length-deformed Schwarzschild spacetime, obtained via the areal-radius substitution $R(r)=\sqrt{r^{2}+\ell^…

Massive open string and totally-noncommutativity in space and momentum coordinates trough Fadeev Jackiw approach
Najim Mansour, El Yamani Diaf, Moulay Brahim Sedra
In this work we will show that it is possible to construct totally noncommuta tivity in the cas of massive bosonic string in an external B-field by extending the well known Faddeev…
