Classical gradient systems have a linear relation between rates and driving forces. In generalized gradient systems we allow for arbitrary relations derived from general non-quadratic dissipation potentials. This paper describes two natural origins for these structures. A first microscopic origin of generalized gradient structures is given by the theory of large-deviation principles. While Markovian diffusion processes lead to classical gradient structures, Poissonian jump processes give rise…

Effective diffusion in thin structures via generalized gradient systems and EDP-convergence

The notion of Energy-Dissipation-Principle convergence (EDP-convergence) is used to derive effective evolution equations for gradient systems describing diffusion in a structure consisting of several

Cross-Diffusion Systems with Excluded-Volume Effects and Asymptotic Gradient Flow Structures

This paper discusses the analysis of a cross-diffusion PDE system for a mixture of hard spheres derived in Bruna and Chapman from a stochastic system of interacting Brownian particles using the method of matched asymptotic expansions.

Gamma-convergence of a gradient-flow structure to a non-gradient-flow structure

We study the asymptotic behaviour of a gradient system in a regime in which the driving energy becomes singular. For this system gradient-system convergence concepts are ineffective. We characterize


The random time-changed Poisson representation for the concentration of each species in chemical reactions is a powerful tool to study macroscopic properties for chemical reactions. The nonlinear

Generalized gradient structures for measure-valued population dynamics and their large-population limit

We consider the forward Kolmogorov equation corresponding to measure-valued processes stemming from a class of interacting particle systems in population dynamics, including variations of the

A gradient system with a wiggly energy and relaxed EDP-convergence

A notion of evolutionary Gamma-convergence is introduced that relates the microscopic energy and the microscopic dissipation potential with their macroscopic limits via Gamma- Convergence.

Decay to Equilibrium for Energy-Reaction-Diffusion Systems

This work derives thermodynamically consistent models of reaction-diffusion equations coupled to a heat equation such that the full coupled system is a gradient flow and proves corresponding entropy-entropy production inequalities with explicitly calculable constants.

We perform a fast-reaction limit for a linear reaction-diffusion system consisting of two diffusion equations coupled by a linear reaction. We understand the linear reaction-diffusion system as a

Revisit of Macroscopic Dynamics for Some Non-equilibrium Chemical Reactions from a Hamiltonian Viewpoint

Most biochemical reactions in living cells are open systems interacting with environment through chemostats to exchange both energy and materials. At a mesoscopic scale, the number of each species in



A gradient structure for reaction–diffusion systems and for energy-drift-diffusion systems

In recent years the theory of the Wasserstein metric has opened up new treatments of diffusion equations as gradient systems, where the free energy or entropy take the role of the driving functional

From a Large-Deviations Principle to the Wasserstein Gradient Flow: A New Micro-Macro Passage

A new connection is established between a system of many independent Brownian particles and the deterministic diffusion equation by proving that Jh and Kh are equal up to second order in h as h → 0.

On evolutionary -convergence for gradient systems

This work investigates the question under which conditions the limits u of (subsequences of) the solutions uε are solutions of the gradient system generated by the Γ-limits E0 and R0.

On the Relation between Gradient Flows and the Large-Deviation Principle, with Applications to Markov Chains and Diffusion

Motivated by the occurrence in rate functions of time-dependent large-deviation principles, we study a class of non-negative functions ℒ that induce a flow, given by ℒ(ρt,ρ̇t)=0$\mathcal{L} (\rho

A gradient structure for systems coupling reaction–diffusion effects in bulk and interfaces

We derive gradient-flow formulations for systems describing drift-diffusion processes of a finite number of species which undergo mass-action type reversible reactions. Our investigations cover

Large deviations and gradient flows

It is indicated that, in some non-equilibrium situations, entropies and thermodynamic free energies can be derived via large-deviation principles.

From Diffusion to Reaction via Γ-Convergence

The aim of this paper is to give a rigorous proof of Kramers's formal derivation and to embed chemical reactions and diffusion processes in a common variational framework which allows one to derive the former as a singular limit of the latter, thus establishing a connection between two worlds often regarded as separate.

Microscopic interpretation of Wasserstein gradient flows

The discovery of Wasserstein gradient flows provided a mathematically precise formulation for the way in which thermodynamic systems are driven by entropy. Since the entropy of a system in


We study the limit of high activation energy of a special Fokker–Planck equation known as the Kramers–Smoluchowski equation (KS). This equation governs the time evolution of the probability density

Chemical Reactions as Gamma-Limit of Diffusion

It is proved that after a suitable rescaling the solution to the Kramers-Smoluchowski equation converges, in the limit of high activation energy, to the solution of a simpler system modeling the spatial diffusion of A and B combined with the reaction A\rightleftharpoons B.
