Developments in normal and gravitational thermodynamics
(24K, TeX)

ABSTRACT.  We review developments in three areas of thermodynamics,
resulting from advances in statistical mechanics and relativity
theory. These concern (a) the resolution of some basic questions,
concerning the thermodynamic variables and the phase structure
of normal matter, (b) thermodynamical
instabilities in non-relativistic gravitational systems, and (c)
Black Hole thermodynamics, as formulated in terms of strictly
observable quantities, and thus not involving any BH entropy
concept.
