Abstract

We study monotone cellular automata (also known as U\mathcal{U}-bootstrap percolation) in Zd\mathbb{Z}^d with random initial configurations. Confirming a conjecture of Balister, Bollob\'as, Przykucki and Smith, who proved the corresponding result in two dimensions, we show that the critical probability is non-zero for all subcritical models.
