Indirect Diffusion Effect and Convergence to Equilibrium

Explore the phenomenon of indirect diffusion effect in reaction-diffusion systems during this 33-minute lecture from the Hausdorff Trimester Program on Kinetic Theory. Delve into the challenges posed by non-diffusing species in chemical reactions and how they impact convergence to equilibrium. Discover how the combination of diffusion from other species and reversible reactions can indirectly create a diffusion effect on non-diffusing species, ultimately driving the entire system towards chemical equilibrium. Gain insights into the entropy method for studying these complex systems and understand the implications of missing Fischer information and logarithmic Sobolev inequality for certain species.
