dc.titleUniversality for critical KCM: finite number of stable directions
dc.typeDocument de travail / Working paper
dc.description.abstractenIn this paper we consider kinetically constrained models (KCM) on Z2 with general update families U. For U belonging to the so-called ``critical class'' our focus is on the divergence of the infection time of the origin for the equilibrium process as the density of the facilitating sites vanishes. In a recent paper Mar\^ech\'e and two of the present authors proved that if U has an infinite number of ``stable directions'', then on a doubly logarithmic scale the above divergence is twice the one in the corresponding U-bootstrap percolation. Here we prove instead that, contrary to previous conjectures, in the complementary case the two divergences are the same. In particular, we establish the full universality partition for critical U. The main novel contribution is the identification of the leading mechanism governing the motion of infected critical droplets. It consists of a peculiar hierarchical combination of mesoscopic East-like motions. Even if each path separately depends on the details of U, their combination gives rise to an essentially isotropic motion of the infected critical droplets. In particular, the only surviving information about the detailed structure of U is its difficulty. On a technical level the above mechanism is implemented through a sequence of Poincaré inequalities yielding the correct scaling of the infection time.
