Let $\rho_{\mathtt{FE}}$ be the critical density of the fixed-energy activated random walk on $\mathbb{Z}^d$, depending on the dimension $d$ and sleep rate $\lambda$, and let…

Let $\zeta_{\mathtt{DD}}$ be the limiting density of the driven-dissipative abelian sandpile model on increasingly large finite boxes, and let $\zeta_{\mathtt{FE}}$ be the critical…

Janssen–Grassberger conjecture. The transition generically belongs to the directed percolation universality class if: (a) it is to a unique absorbing state from a fluctuating activ…
