This equation's namesake called one of its terms, the "cosmological constant," the "biggest blunder of his life," but now astrophysicists interpret that term of these equations as dark energy.
A lapse function and a shift vector field are used in a "numerical" approach to solving these equations called the ADM formalism. The linearized form of these equations is in terms of the d'Alembertian (dal-ahm-BARE-shin) of a tensor often represented with an "h" that satisfies the harmonic coordinate condition. In geometrized units, this equation is "big-G-sub-mu-nu plus lambda little-g-sub-mu-nu equals 8-pi-T-sub-mu-nu." This set of ten nonlinear, partial differential equations is often presented as a tensor equation. This equation's namesake called one of its terms, the "cosmological constant," the "biggest blunder of his life," but now astrophysicists interpret that term of these equations as dark energy. For 10 points, name these eponymous equations used to describe the interaction of energy and spacetime curvature in general relativity.
