The Einstein equation is derived from the proportionality of entropy and horizon area together with the fundamental relation Î´Q = TdS connecting heat, entropy, and temperature. The key idea is toâ€¦ (More)

Two techniques for computing black hole entropy in generally covariant gravity theories including arbitrary higher derivative interactions are studied. The techniques are Waldâ€™s Noether chargeâ€¦ (More)

We study the spectrum of created particles in two-dimensional black hole geometries for a linear, hermitian scalar field satisfying a Lorentz non-invariant field equation with higher spatialâ€¦ (More)

Vegetative (or heterokaryon) incompatibility is often characterized by cell death after anastomosis. In Neurospora crassa, partial diploid strains heterozygous for a single heterokaryonâ€¦ (More)

A derivation of the Hawking effect is given which avoids reference to field modes above some cutoff frequency Ï‰c â‰« Mâˆ’1 in the freefall frame of the black hole. To avoid reference to arbitrarily highâ€¦ (More)

We examine the Zeroth Law and the Second Law of black hole thermodynamics within the context of effective gravitational actions including higher curvature interactions. We show that entropy can neverâ€¦ (More)
