First-passage competition with different speeds: positive density for both species is impossible
First-passage competition with different speeds: positive density for both species is impossible
Consider two epidemics whose expansions on $\mathbb{Z}^d$ are governed by two families of passage times that are distinct and stochastically comparable. We prove that when the weak infection survives, the space occupied by the strong one is almost impossible to detect. Particularly, in dimension two, we prove that one species …
