# Gradient and GENERIC Systems in the Space of Fluxes, Applied to Reacting Particle Systems

@article{Renger2018GradientAG, title={Gradient and GENERIC Systems in the Space of Fluxes, Applied to Reacting Particle Systems}, author={Michiel Renger}, journal={Entropy}, year={2018}, volume={20} }

In a previous work we devised a framework to derive generalised gradient systems for an evolution equation from the large deviations of an underlying microscopic system, in the spirit of the Onsager–Machlup relations. Of particular interest is the case where the microscopic system consists of random particles, and the macroscopic quantity is the empirical measure or concentration. In this work we take the particle flux as the macroscopic quantity, which is related to the concentration via a…
