Stationary reaction-diffusion systems in L^1 revisited

Abstract

We prove existence of \begin{document}$ L^1 $\end{document} -weak solutions to the reaction-diffusion system obtained as a stationary version of the system arising for the evolution of concentrations in a reversible chemical reaction, coupled with space diffusion. This extends a previous result by the same authors where restrictive assumptions on the number of chemical species are removed.
