Entropy of spacelike two-surfaces of spacetime
Jun, 2004Citations per year
Abstract: (arXiv)
We argue that every finite piecewise smooth spacelike two-surface of spacetime possesses an entropy which is, in natural units, one quarter of its area. However, the thermodynamical properties of a two-surface become apparent only to the observers having that two-surface as a horizon. Consequences of this result are discussed.References(11)
