Equivalence of Hawking and Unruh temperatures and entropies through flat space embeddings

We present a unified description of temperature and entropy in spaces with either 'true' or 'accelerated observer' horizons: In their (higher-dimensio nal) global embedding Minkowski geometries, the relevant detectors have con stant accelerations a(G); associated with their Rindler horizons are temper ature a(G)/2 pi and entropy equal to 1/4 of the horizon area. Both quantiti es agree with those calculated in the original curved spaces. As one exampl e of this equivalence, we obtain the temperature and entropy of Schwarzschi ld geometry from its flat D = 6 embedding.
