A note on the diffusive scaling limit for a class of linear systems. (English) Zbl 1193.60121
Summary: We consider a class of continuous-time stochastic growth models on $$d$$-dimensional lattice with non-negative real numbers as possible values per site. We remark that the diffusive scaling limit proven in our previous work [Electron. J. Probab. 14, 960–977, electronic only (2009; Zbl 1189.60181)] can be extended to wider class of models so that it covers the cases of potlatch/smoothing processes.
