Title: Noether Conserved Quantities in Teleparallel Equivalents of General Relativity
Abstract: Teleparallel equivalents of general relativity describe gravity in terms of torsion (TEGR) or nonmetricity (STEGR), rather than curvature. In this talk, I will review the construction of covariant Noether currents, superpotentials, and conserved charges in both formulations. Particular attention will be paid to the role of teleparallel connections, gauge choices, and observers in defining gravitational energy and momentum. I will illustrate the formalism through applications to Schwarzschild and Kerr black holes, cosmological solutions, and gravitational waves, discussing the physical interpretation of conserved quantities and their relation to the equivalence principle.
