Infinite Dimensional Reaction-diffusion Processes

<正> §1.IntroductionThe background of the reaction-diffusion processes can be found in Haken andYan and Lee.For finite dimensional case,the reaction-diffusion processes havebeen studied by Yan and Chen.In particular,it has been proved there that theprocess corresponding to Schlgl model is always ergodic,hence the invariantmeasure is unique,so there is no phase transition.Howeyer,many physists think
