Central limit theorem for a class of linear systems. (English) Zbl 1189.60181
Summary: We consider a class of interacting particle systems with values in [$$0,\infty )^{\mathbb{Z}^{d}}$$, of which the binary contact path process is an example. For d $$\geq 3$$ and under a certain square integrability condition on the total number of the particles, we prove a central limit theorem for the density of the particles, together with upper bounds for the density of the most populated site and the replica overlap.
