The concept of entropy. Relation between action and entropy
The Boltzmann expression for entropy represents the traditional link between thermodynamics and statistical mechanics. New theoretical developments like the Unruh effect or the black hole theory suggest a new definition of entropy. In this paper we consider the thermodynamics of black holes as s...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The Boltzmann expression for entropy represents the traditional link between
thermodynamics and statistical mechanics. New theoretical developments
like the Unruh effect or the black hole theory suggest a new definition
of entropy. In this paper we consider the thermodynamics of black
holes as seriously founded and we try to see what we can learn from it in
the case of ordinary systems for which a pre-relativistic description is sufficient. We introduce a space-time model and a new definition of entropy
considering the thermal equilibrium from a dynamic point of view. Then we
show that for black hole and ordinary systems we have the same relation
relating a change of entropy to a change of action. |
