In science:
The SLDNFA-system, which is one of the solvers developed in the pro ject to reason on ID-logic theories, is an integration of abductive logic programming (Kakas, Kowalski, & Toni 1993) and constraint logic programming (Jaffar & Maher 1994).
SLDNFA-system
ID-logic generalizes not only classical logic but also abductive logic programming (Kakas, Kowalski, & Toni 1993) and open logic programming (Denecker 1995).
SLDNFA-system
As for the dispersion variant conditions : relation (18), in terms of ka it takes the form √kaka = ± m(1 − r) [(νik i )2/kj k j ]r/2 .
Concerning the generalized Lorentz symmetry and the generalization of the Dirac equation
The proof of this is as follows: Since kaka is constant and zero on the Killing horizon by deﬁnition, then ∇b(kaka) must be normal to the horizon, in the sense of being orthogonal to any vector tangent to a curve lying in the horizon.
Dynamical surface gravity
The Killing horizon is located where the Killing vector ka becomes null, kaka = 0.
Black holes and black hole thermodynamics without event horizons
On the Killing horizon it is null by deﬁnition, kaka = 0, but its derivative is not necessarily zero at the horizon ∇b (kaka ) 6= 0 since the Killing vector is not necessarily null away from the horizon.
Black holes and black hole thermodynamics without event horizons
However, the vector ∇b (kaka ) will be normal to the Killing horizon in the sense that it will be orthogonal to any vector that is tangent to a curve lying in the horizon.
Black holes and black hole thermodynamics without event horizons
This κ can be taken to be the surface gravity if the Killing vector is suitably normalized, which is usually achieved by demanding kaka = −1 at spatial inﬁnity.
