Viscous fluid analogy<br />
Null limit (<strong>event</strong> horizon)<br />
If H is a null hypersurface,<br />
h = m = ℓ and C = 0<br />
and we recover the original Damour-Navier-S<strong>to</strong>kes equation:<br />
S Lℓ Ω (ℓ) + θ (ℓ) Ω (ℓ) = Dκ − D · σ (ℓ) + 1<br />
2 Dθ(ℓ) + 8πq ∗ T · ℓ<br />
