# Mathematical consequences of Gyarmati’s principle in rational thermodynamics

@article{Lucia1995MathematicalCO, title={Mathematical consequences of Gyarmati’s principle in rational thermodynamics}, author={Umberto Lucia}, journal={Il Nuovo Cimento B (1971-1996)}, year={1995}, volume={110}, pages={1227-1235} }

SummaryThe calculus of variations can be applied in thermodynamics obtaining both local and global analysis for the thermodynamical systems. Gyarmati’s principle is demonstrated to be the mathematical fundamental of the theorem of maximum for the entropy of the open systems. This last theorem is demonstrated for a general thermodynamical transformation, and also when chemical reactions can occur.
