The Frog Model on $Z$ with Discrete Weibull Lifetimes and Random Parameter $p$

J. H. Ramírez González, Gustavo O. Carvalho, Fábio P. Machado

We study the frog model on $Z$ with particle wise discrete Weibull lifetimes. Each particle has an i.i.d. survival parameter $π \in (0, 1)$ ; conditionally on $π = p$ , its lifet…

The Frog Model on $Z$ with General Random Survival Parameter

Gustavo O. Carvalho, Fábio P. Machado, J. Hermenegildo R. González

We study the frog model on $Z$ with particle-wise random geometric lifetimes: each particle has a survival parameter $π \in (0, 1)$ sampled i.i.d., whose density near $1$ sat…

Frog model on $Z$ with random survival parameter

Gustavo O. de Carvalho, Fábio P. Machado

We study the frog model on $ \mathbb{Z} $ with geometric lifetimes, introducing a random survival parameter. Active and inactive particles are placed at the vertices of \( \mathb…
