Mapping Schwarzschild, de Sitter and anti-de Sitter spacetimes into flat spacetime systems with Kratzer potentials
MD de Oliveira, AGM Schmidt - Annals of Physics, 2025 - Elsevier
This work investigates a method to map systems with gravitational fields into non-relativistic
flat spacetime ones. Considering a line element of the form ds 2= e 2 f (r) dt 2− e 2 g (r) dr 2 …
