Symmetry and Conserved Quantities in $f(R)$-Gravity: Mei vs. Noether Approaches

Tahia F. Dabash, Moataz H. Emam, Lukas Schoppner

We study the symmetries and conserved quantities in $f(R)$ gravity for the static, spherically symmetric Reissner--Nordström spacetime using two complementary frameworks: Noether…
